Hello, I want to report this bug. My OS - Kicksecure, based on Debian. https://www.kicksecure.com/ Tor Browser version - 12.0.1 Security level - safer Steps for reproduction - copy and paste any websearch request to search bar, click on Startpage icon in the search bar menu, then https://localhost/ appears in the search bar as if Tor Browser tried to contact localhost instead of startpage. The issue may not be readily reproduced 100% of all the times, it comes up very rarely when I do some web search.  This all can happen if I use either a custom search engine for a single websearch request or with default search engine. This is metager onion link for me. Note that Tor Browser may sometimes mistake clearnet link for a hidden service instead of localhost. In such case it would only display a standard built-in page that says hidden service with such name is not found.
