User support report for September 2025
by ebanam 14 Oct '25

14 Oct '25

Hello everyone, This is the report from user support team for the month of September. Note: (↑), (↓) and (-) are indicating if the number of tickets we received for these topics have been increasing, decreasing or have been the same from the previous month respectively. - Summary of updates from user support - Farsi-speaking user support - Russian-speaking user support - General user support - Frontdesk (email user support channel) - Telegram, WhatsApp and Signal user support channels - Topics from the Tor Forum - Highlights from Google Play Store # Summary of updates from user support * With the release of Tor VPN Beta, we have received number of questions on how to get started testing the app, signing up for the beta through Play Store, questions and feedback about the app as well as help with troubleshooting on the Tor Forum [1] and other support channels. We are keeping track of these requests and feedback on our bug tracker.[2] * Last month, we answered a significant number of support requests for WebTunnel bridges. For some context, newer Telegram accounts were unable to request these bridges directly from our Telegram Bridge Distributor (@GetBridgesBot) and were therefore encouraged to contact us on our support channels. With the Telegram distributor now sharing WebTunnel bridges with all Telegram users [3], we are noticing a big drop in such requests in October. A big shoutout to onyinyang for implementing these changes to the Telegram Bridge Distributor! ## Farsi-speaking user support * 88 tickets in total (↓3 as compared to August) * 83 tickets on Telegram * 5 tickets on Email ## Russian-speaking user support * 2045 tickets in total (↓234 as compared to August) * 1883 tickets on Telegram * 160 tickets on Email * 2 tickets on Signal * In recent months, we've noticed that among the group of Russian-speaking users, we're now also receiving bridge requests every month from users in Belarus. Although the Tor usage in the country on Tor Metrics appears normal, we don't know whether some parts of Tor are being blocked there, and further investigation into possible Tor censorship in the country is needed. * On the Tor Forum, Russian users pointed out a new 'whitelisting' method being implemented in the country and how Tor is unable to connect during the 'curfew' hours.[4] ## General user support * 927 tickets in total (↓159 as compared to August) * 504 tickets on Email * 405 tickets on Telegram * 18 tickets on Signal * Bridges with WebTunnel pluggable transport working most reliably for users in China, we received a number of tickets with queries on how to obtain such bridges and how to use them in Tor Browser and Tails. That's it for the summary, following is a more detailed report about the tickets our user support team worked on last month. # Frontdesk (email user support channel) * 605(↓) RT tickets created * 669(↑) RT tickets resolved Tickets by topics and numbers: 1. 309(↓) tickets: instructions to circumvent censorship for Chinese speaking users. 2. 160(↓) tickets: circumventing censorship in Russian speaking countries. 3. 54(↑) tickets: help with troubleshooting existing Tor Browser install on Desktop (Windows, macOS and Linux). 4. 15(↑) tickets: questions, feedback and help with troubleshooting Tor VPN beta. 5. 7(↑) tickets: questions about which Tor app to install on iOS (i.e. Onion Browser or Orbot). 6. 5(↑) tickets: circumventing censorship with Tor in Farsi. 7. 3(↓) tickets: help with troubleshooting existing Tor Browser install on Android. 8. 3(↑) tickets: help with instructions to download, install or properly uninstalling Tor Browser. 9. 3(↑) tickets: reports of websites blocking Tor connections or not performing well in Tor Browser. 10. 3(↑) tickets: reports of email bridge distributor (bridges(a)torproject.org) not responding. The issue is resolved. 11. 3(↑) tickets: reports of DuckDuckGo's HTML page and search results displayed incorrectly on Safest security level.[5] 12. 2(-) tickets: question about onion services and how to access them. 13. 2(↑) tickets: reports of fake apps on iOS AppStore masquerading as official Tor Browser. 14. 2(↑) tickets: users seeing a "proxy refused" error when visiting websites on Tor Browser for Android using Samsung devices. 15. 2(↑) tickets: question about changes to the Security level settings on latest versions of Tor Browser. The browser prompts a restart when changing the Security Level for changes to properly take effect. 16. 2(↑) tickets: instructions to download Tor Browser 13.5 legacy for legacy operating systems. 17. 2(↑) tickets: question about installing extensions and add-ons on Tor Browser. 18. 1(-) ticket: help with installing Tor Browser on Desktop on Linux. 19. 1(↑) ticket: help with verifying Tor Browser's GPG signature. 20. 1(↑) ticket: report of Tor Browser conflicting with anti-virus installed on users' device. (It was a false alarm and the issue is resolved). 21. 1(↑) ticket: question on how DNS resolution works when using Tor (Browser). 22. 1(↑) ticket: help with setting up a Tor relay. # Telegram, WhatsApp and Signal user support channels * 2391(↓) tickets resolved Breakdown: * 2371(↓) tickets on Telegram * 20(↑) tickets on Signal * No tickets on WhatsApp Tickets by topics and numbers: 1. 1885(↓) tickets: circumventing censorship in Russian speaking countries. 2. 155(↓) tickets: WebTunnel bridge requests from users with newer Telegram accounts and unable to receive one from the @GetBridgesBot on Telegram. 3. 202(↓) tickets: instructions to circumvent censorship for Chinese speaking users. Note: There is a significant overlap in the WebTunnel bridge request tickets on our support channels and support requests from Russian and Chinese speaking users. 4. 83(↓) tickets: circumventing censorship with Tor in Farsi. 5. 36(↑) tickets: instructions to use WebTunnel bridges with Tor Browser. 6. 22(↑) tickets: questions, feedback and help with troubleshooting Tor VPN beta. 7. 20(↓) tickets: helping users on iOS, using Onion Browser or Orbot, to use censorship circumvention methods. 8. 12(↑) tickets: help with instructions to troubleshoot Tails operating system. 9. 7(↓) tickets: instructions on how to get Tor Browser binaries from GetTor. 10. 5(↑) tickets: questions about onion services and how to access them. 11. 10(↓) tickets: help with troubleshooting Tor Browser Desktop on Windows, macOS and Linux. 12. 4(↓) tickets: help with using Snowflake with Tor to circumvent censorship. 13. 3(↓) tickets: users seeing a "proxy refused" error when visiting websites on Tor Browser for Android using Samsung devices. 14. 3(↑) tickets: help with installing Tor Browser on Desktop on Linux. 15. 3(↓) tickets: help with troubleshooting Tor Browser Android. 16. 2(↓) tickets: help with instructions to use bridges with Orbot on Android. 17. 2(↑) tickets: instructions to download Tor Browser 13.5 legacy for legacy operating systems. 18. 2(↑) tickets: help with troublehsooting tor, the network daemon, aka little-t tor. 19. 1(↓) ticket: instructions to verify Tor Browser's GPG signature. 20. 1(↑) ticket: reports of DuckDuckGo's HTML page and search results displayed incorrectly on Safest security level. 21. 1(↑) ticket: can't install Tor Browser for macOS when downloading the dmg file from Telegram GetTor.[6] # Topics from the Tor Forum * Help us test the new Tor User Support Portal.[7] Highlighting some other discussion topics and, in general, frequently asked questions on our support forums: * Should I set Tor Browser as my default browser? [8] * Tor support and discussion channel.[9] * Images uploaded on Tor Browser (Desktop and Android) are randomized for Canvas Fingerprinting protection.[10] # Highlights from Google Play Store * Tor Browser for Android (TBA) had a Google Play rating of 4.4 (↑0.008) stars in September, which is higher as compared to in August. * In September, Tor Browser for Android (TBA) got 724 (↓46) new reviews. The total count of reviews for the app stands at 65,186. * Tor Browser for Android Alpha (TBA Alpha) app had a rating of 4.196 (↑0.016) in September, which is higher as compared to in August. * In September, Tor Browser for Android Alpha (TBA Alpha) got 32 (↑2) new reviews. The total count of reviews for the app stands at 8,671. * The major concern that Tor Browser users express in the comments is regarding the browsing speed. This issue is currently under investigation [11]. * Also there are many comments from users in regions where Tor is censored and whenever possible, we are encouraging users to reach out to our support channels directly.

Are there some obvious grouping strategies that we can already consider? e.g., by PT, by bandwidth (lower bandwidth bridges sacrificed to open-invitation buckets?), by locale (to be matched with a requesting user's geoip or something?) 2. Does it make sense to group 3 bridges/bucket, so trusted users have access to 3 bridges (and untrusted users have access to 1)? More? Less? theodorsm: 2025-06-12 Last weeks: - Applying for funding from NLnet to implement DTLS 1.3 in Pion. Got through the first round. - Writing paper for FOCI: continuation of master thesis about reducing distinguishability of DTLS in Snowflake by implementing covert-dtls, further analysis of collected browser fingerprint and stability test of covert-dtls in snowflake proxies. Draft: https://theodorsm.net/FOCI25 - Key takeaways: * covert-dtls is stable when mimicking DTLS 1.2 handshakes, while the randomization approach— though more resistant to fingerprinting — tends to be less stable. * Chrome webextensions are more unstable than standalone proxies * covert-dtls should be integrated in Snowflake proxies as they produce the ClientHello messages during the DTLS handshake. * Chrome randomizes the order of extension list. * Firefox uses DTLS 1.3 by default in WebRTC. * A prompt adoption of DTLS 1.3 in both Snowflake and our fingerprint-resistant library is needed to keep up with browsers * The evolution of browsers’ fingerprints had no noticeable effect on Snowflake’s number of daily users over the last year. * Even with a sharp drop in the amount of proxies, it does not seem to affect the number of Snowflake users. * Browser extensions make Snowflake resistant to ClientHello fingerprinting. * Standalone proxies can serve more Snowflake clients per volunteer than webextensions. * We need metrics on which types of proxies are actually being matched and successfully used by clients. Next weeks: - Getting paper camera ready. - Fix merge conflicts in MR (https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow…) Help with: - Should we do user testing of covert-dtls?

Soft release - Help us test the new Tor User Support portal!
by gus 06 Oct '25

06 Oct '25

Hello everyone, This week we're soft releasing the new Tor User Support portal! Please help us test it and report any issues you find. ## Background Over the past month, we've been migrating the content from Tor Browser User Manual and the (old) Support portal into a new single, unified resource, the new Support portal. Our goal is simple: to give Tor users one place where they can find support information about our products. After this migration, tb-manual.torproject.org will redirect to support.torproject.org. ## How to help 1. Visit and browse the new staging website on your favorite platforms: https://tor-www@support.staging.torproject.net 2. Found an issue or have feedback? - First, check if it's already reported, - If not, open a new issue here: https://gitlab.torproject.org/tpo/web/marble/support/-/issues 3. Or if you prefer to chat, join us on Matrix: #tor-www:matrix.org / #tor-www on irc.oftc.net. ## Localization Because we moved and adapted the website content, we'll need new translations. Please use Weblate to translate the new support website into your language! https://hosted.weblate.org/projects/tor/new-support-portal/ ## Next steps After this soft release, we're planning to officially announce the new Support portal next week on our blog, so your feedback now will help us make it ready for everyone. Thank you for your help! cheers, Gus -- The Tor Project Community Team Lead

For this, just being able to pass multiple bindaddrs would suffice. * Another desired feature: run a single bridge with many listening IP addresses, an IPv4 /24 or IPv6 /56 for example. * Where to send a written-up change proposal? * There is a repo for spec proposals, https://gitlab.torproject.org/tpo/core/torspec/, but for this it's probably better to write it up in https://gitlab.torproject.org/tpo/anti-censorship/bridgestrap/-/issues/48. * "for the format changes, i would suggest specing out what those would look like more precisely and the changes they'd require in onionoo and metrics so that meskio and someone from the metrics team can review it and discuss" == Actions == * Remove webtunnel setuid script in 3 weeks.(decrease this by one every week) == Interesting links == * == Reading group == * We will discuss "The Internet Coup" on October 23rd * https://interseclab.org/wp-content/uploads/2025/09/The-Internet-Coup_Septem… * Particularly relevant sections: "Blocking online privacy and circumvention tools" section of InterSecLab report on Geedge Networks, mentions Tor, Snowflake, WebTunnel * Notes: https://github.com/net4people/bbs/issues/519#issuecomment-3282101626 * Questions to ask and goals to have: * What aspects of the paper are questionable? * Are there immediate actions we can take based on this work? * Are there long-term actions we can take based on this work? * Is there future work that we want to call out in hopes that others will pick it up? == Updates == Name: This week: - What you worked on this week.

User Support Report for August 2025
by ebanam 15 Sep '25

15 Sep '25

Hello everyone, This is the report from user support team for the month of August. Note: (↑), (↓) and (-) are indicating if the number of tickets we received for these topics have been increasing, decreasing or have been the same from the previous month respectively. - Summary of updates from user support - Farsi-speaking user support - Russian-speaking user support - General user support - Frontdesk (email user support channel) - Telegram, WhatsApp and Signal user support channels - Topics from the Tor Forum - Highlights from Google Play Store # Summary of updates from user support * With our Telegram Bridge Distributor (@GetBridgesBot) now sharing WebTunnel bridges[1] and bridges with WebTunnel pluggable transport working most reliably in censored regions like Russia and China, newer Telegram accounts[2] are unable to request these bridges directly from the bot. Users with new accounts are therefore encouraged to contact us on our support channels. As a result, last month alone we responded to 224 users with this issue. We have opened a ticket for the anti-censorship team[3] reporting this urgent issue. * We also provided feedback[4] and worked with anti-censorship team to improve the workflow for users interacting with the Telegram Bridge distributor, including some adjustments[5] to the user interface. ## Farsi-speaking user support * 91 tickets in total (↑8 as compared to July) * 89 tickets on Telegram * 2 tickets on Email ## Russian-speaking user support * 2279 tickets in total (↑24 as compared to July) * 2082 tickets on Telegram * 191 tickets on Email * 3 tickets on WhatsApp * 3 tickets on Signal * August marked a record high in user support requests coming from Russian-speaking users. Among Russian users, the main problem is that obfs4 is blocked on certain mobile networks. The recommended workaround - using WebTunnel bridges - has also been impacted, as since June these have been blocked through SNI filtering, and other bridges have likewise been affected by DPI rules targeting OVH, Hetzner, and Linode/DigitalOcean infrastructure. The difficulty of finding an unblocked bridge to access Tor has become a major pain point for Russian users and is significantly increasing the load on our support channels. ## General user support * 1086 tickets in total (↑365 as compared to July) * 461 tickets on Email * 606 tickets on Telegram * 8 tickets on WhatsApp * 11 tickets on Signal * Massive uptick in user support requests from users trying to connect to Tor from Chinese-speaking users on our Telegram user support channel. This can be attributed to the fact that with WebTunnel working most reliably in China, users with newer Telegram accounts are unable to get WebTunnel bridges and reaching out on the support channels. That's it for the summary, following is a more detailed report about the tickets our user support team worked on last month. # Frontdesk (email user support channel) * 728(↓) RT tickets created * 654(↑) RT tickets resolved Tickets by topics and numbers: 1. 377(↓) tickets: instructions to circumvent censorship for Chinese speaking users. 2. 191(↓) tickets: circumventing censorship in Russian speaking countries. 3. 47(↓) tickets: help with troubleshooting existing Tor Browser install on Desktop (Windows, macOS and Linux). 4. 5(-) tickets: help with troubleshooting existing Tor Browser install on Android. 5. 4(↑) tickets: questions about which Tor app to install on iOS (i.e. Onion Browser or Orbot) 6. 2(↓) tickets: circumventing censorship with Tor in Farsi. 7. 2(↑) tickets: question about onion services and how to access them. 8. 2(↑) tickets: help with instructions to download and install Tor Browser. 9. 2(↑) tickets: instructions on how to get Tor Browser binaries from GetTor. 10. 1(↓) ticket: help with installing Tor Browser on Desktop on Linux. 11. 1(↓) ticket: reports of fake apps on iOS AppStore masquerading as official Tor Browser. 12. 1(↑) ticket: question about what are "Bridges" in Tor Browser and what purpose they serve. # Telegram, WhatsApp and Signal user support channels * 2796(↑) tickets resolved Breakdown: * 2771(↑) tickets on Telegram * 11(-) tickets on WhatsApp * 14(↑) tickets on Signal Tickets by topics and numbers: 1. 2082(↑) tickets: circumventing censorship in Russian speaking countries. 2. 224(↑) tickets: WebTunnel bridge requests from users with newer Telegram accounts and unable to receive one from the @GetBridgesBot on Telegram. 3. 221(↑) tickets: instructions to circumvent censorship for Chinese speaking users. 4. 89(↑) tickets: circumventing censorship with Tor in Farsi. 5. 27(↑) tickets: helping users on iOS, using Onion Browser or Orbot, to use censorship circumvention methods. 6. 18(↑) tickets: help with troubleshooting Tor Browser Android. 7. 17(-) tickets: help with troubleshooting Tor Browser Desktop on Windows, macOS and Linux. 8. 17(↑) tickets: instructions on how to get Tor Browser binaries from GetTor. 9. 8(↑) tickets: help with using Snowflake with Tor to circumvent censorship. 10. 7(↑) tickets: help with instructions to use bridges with Tails. 11. 6(↑) tickets: help with instructions to use bridges with Orbot on Android. 12. 4(↑) tickets: users seeing a "proxy refused" error when visiting websites on Tor Browser for Android using Samsung devices. 13. 4(↑) tickets: instructions to verify Tor Browser's GPG signature. 14. 2(↓) tickets: questions about onion services and how to access them. 15. 1(↓) ticket: instructions to download Tor Browser 13.5 legacy for legacy operating systems. # Topics from the Tor Forum * Web Authentication (WebAuthn) and Universal 2nd Factor (U2F) (i.e. YubiKey) support is disabled in Tor Browser.[6] Couple of discussions about installing/running Tor Browser on Linux which we sometimes get asked about on our other user support channels as well: * Folder access permissions after installing Tor Browser on Linux.[7] * Executable permission error when installing Tor Browser on Linux.[8] # Highlights from Google Play Store * Tor Browser for Android (TBA) had a Google Play rating of 4.392 (↑0.009) stars in August, which is higher as compared to in July. * Tor Browser for Android (TBA) got 770 (↓6) new reviews. The total count of reviews for the app stands at 64,625. * Tor Browser for Android Alpha (TBA Alpha) app had a rating of 4.18 (↑0.002) which is higher as compared to in July. * In August, Tor Browser for Android (TBA Alpha) got 30 (↓2) new reviews. The total count of reviews for the app stands at 8,649. The major complaints we are receiving in the comments are about Tor Browser for Android being slow to browse. We are actively investigating[9] this issue for instances where it's clear that it's not a censorship-circumvention related issue and when the user has already tried some basic steps like refreshing the Tor circuit. We are also receiving a lot of comments from Russian-speaking users experiencing issues connecting to Tor. We are sharing instructions that will work for them and directing them to our user support channels.

Are there some obvious grouping strategies that we can already consider? e.g., by PT, by bandwidth (lower bandwidth bridges sacrificed to open-invitation buckets?), by locale (to be matched with a requesting user's geoip or something?) 2. Does it make sense to group 3 bridges/bucket, so trusted users have access to 3 bridges (and untrusted users have access to 1)? More? Less? theodorsm: 2025-06-12 Last weeks: - Applying for funding from NLnet to implement DTLS 1.3 in Pion. Got through the first round. - Writing paper for FOCI: continuation of master thesis about reducing distinguishability of DTLS in Snowflake by implementing covert-dtls, further analysis of collected browser fingerprint and stability test of covert-dtls in snowflake proxies. Draft: https://theodorsm.net/FOCI25 - Key takeaways: * covert-dtls is stable when mimicking DTLS 1.2 handshakes, while the randomization approach— though more resistant to fingerprinting — tends to be less stable. * Chrome webextensions are more unstable than standalone proxies * covert-dtls should be integrated in Snowflake proxies as they produce the ClientHello messages during the DTLS handshake. * Chrome randomizes the order of extension list. * Firefox uses DTLS 1.3 by default in WebRTC. * A prompt adoption of DTLS 1.3 in both Snowflake and our fingerprint-resistant library is needed to keep up with browsers * The evolution of browsers’ fingerprints had no noticeable effect on Snowflake’s number of daily users over the last year. * Even with a sharp drop in the amount of proxies, it does not seem to affect the number of Snowflake users. * Browser extensions make Snowflake resistant to ClientHello fingerprinting. * Standalone proxies can serve more Snowflake clients per volunteer than webextensions. * We need metrics on which types of proxies are actually being matched and successfully used by clients. Next weeks: - Getting paper camera ready. - Fix merge conflicts in MR (https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snow…) Help with: - Should we do user testing of covert-dtls?

minutes from the sysadmin meeting
by Antoine Beaupré 09 Sep '25

09 Sep '25

Time for your monthly dose of sysadmin minutes! # Roll call: who's there and emergencies all team present, no emergencies ## Normal per-user check-in we went through our normal check-in * https://gitlab.torproject.org/groups/tpo/-/boards?scope=all&utf8=%E2%9C%93&… * https://gitlab.torproject.org/groups/tpo/-/boards?scope=all&utf8=%E2%9C%93&… * https://gitlab.torproject.org/groups/tpo/-/boards?scope=all&utf8=%E2%9C%93&… * https://gitlab.torproject.org/groups/tpo/-/boards?scope=all&utf8=%E2%9C%93&… * https://gitlab.torproject.org/groups/tpo/-/boards?scope=all&utf8=%E2%9C%93&… ## General dashboards We noticed a lot of untriaged issues in the web boards, and @lelutin is a little overloaded, so we picked issues off his board. * https://gitlab.torproject.org/tpo/tpa/team/-/boards/117 * https://gitlab.torproject.org/groups/tpo/web/-/boards * https://gitlab.torproject.org/groups/tpo/tpa/-/boards # Roadmap review anarcat mentioned that we need to review Q3 and plan Q4 in the next monthly meeting. keep in mind that what we don't do from the 2025 roadmap in q4 will get postponed to 2026, and that has an influence on the tails merge roadmap! we would really like to finish the puppet merge this year, at least. we hope to start brainstorming a proper 2026 roadmap in october. # Other discussions ## state of the onion do we do it? what do we want to present? we haven't presented for the last two years, didn't seem to cause an issue for the grand public, no one asked us for it... maybe we could do a talk to TPI/TPO directly instead of at the SOTO? But then again, not talking contributes to an invisibilisation of our work... It's important for the world to know that developers need help to do their work and sysadmins are important: this organization wouldn't *immediately* collapse if we would go away, but it would certainly collapse *soon*. It's also important for funders to understand (and therefore fund) our work! Ideas of things to talk about: - roadmap review? we've done a lot of work this year, lots of things we could talk about - asncounter? - interactions with upstreams (debian, puppet, gitlab, etc) - people like anecdotes: wrong gitlab shrink? mailman3 memory issues and fix anarcat will try to answer the form and talk with pavel for some help on next steps. # Next meeting as usual, first monday of october. # Metrics of the month * host count: 99 * number of Apache servers monitored: 33, hits per second: 696 * number of self-hosted nameservers: 6, mail servers: 99 * pending upgrades: 0, reboots: 99 * average load: 1.62, memory available: 4.6 TB/7.2 TB, running processes: 240 * disk free/total: 88.7 TB/204.3 TB * bytes sent: 514.4 MB/s, received: 334.0 MB/s * [GitLab tickets][]: 244 tickets including... * open: 0 * ~Roadmap::Icebox: 130 * ~Roadmap::Future: 44 * ~Needs Information: 3 * ~Roadmap::Backlog: 38 * ~Roadmap::Next: 12 * ~Roadmap::Doing: 15 * ~Needs Review: 3 * (closed: 4198) * [~Technical Debt][]: 12 [Gitlab tickets]: https://gitlab.torproject.org/tpo/tpa/team/-/boards [~Technical Debt]: https://gitlab.torproject.org/groups/tpo/tpa/-/issues/?state=opened&label_n… Upgrade prediction graph lives at https://gitlab.torproject.org/tpo/tpa/team/-/wikis/howto/upgrades/trixie/ We've past our estimated finish date for the trixie upgrades (2025-08-06), which means we've slowed down quite a bit in our upgrade batches. But we're close to completion! We're still hoping to finish in 2025, but it's possible this drags into 2026. -- Antoine Beaupré torproject.org system administration
