Pier Angelo Vendrame pushed to branch tor-browser-128.7.0esr-14.5-1 at The Tor Project / Applications / Tor Browser

Commits: 6c4f2b1c by Henry Wilkes at 2025-02-10T16:10:58+00:00 fixup! TB 41435: Add a Tor Browser migration function

TB 43462: Drop preference for blocking internet tests since it no longer requires Moat access.

- - - - - 3e08adbf by Henry Wilkes at 2025-02-10T16:10:59+00:00 fixup! TB 31286: Implementation of bridge, proxy, and firewall settings in about:preferences#connection

TB 43462: Make the internet status in `about:preferences` update automatically without any user input.

We listen to the status via TorConnect.

- - - - - f3a86166 by Henry Wilkes at 2025-02-10T16:10:59+00:00 fixup! Tor Browser strings

TB 43462: Add a string for the "unknown" internet status.

- - - - - b97265e0 by Henry Wilkes at 2025-02-10T16:12:36+00:00 fixup! TB 40597: Implement TorSettings module

TB 43462: Use NetworkLinkService instead of Moat for the internet test.

TorConnect now exposes an `internetStatus` property, which is kept up to date using `NetworkLinkService`.
