Warn users that already have bridges that auto-bootstrapping will remove them
From #41621 (comment 3024413).
Currently if your first bootstrap fails, "about:torconnect" will suggest using a bridge to connect (auto-bootstrapping). If the user chooses this and it succeeds, the bridges that worked will replace their current bridges (if any). And this may not be easily reverted if the user previously added bridges directly, or received them from "Request bridges", or has a bridge pass (Lox).
In the case where the user already has bridges, we could let them know in "about:torconnect" that using auto-bootstrapping will remove whatever bridges they currently use. And this might not be reversible. Maybe give them the option to visit the connection settings to review their current bridges instead, and allow them to retry normal bootstrapping.
Another scenario to consider is if bootstrapping fails when the user has bridges configured but they are not enabled. We could let them know and give them an option to enable their bridges and retry normal bootstrapping.
