Pier Angelo Vendrame pushed to branch tor-browser-115.5.0esr-13.0-1 at The Tor Project / Applications / Tor Browser

Commits: 92139ee5 by Pier Angelo Vendrame at 2023-12-04T12:57:25+01:00 fixup! Bug 31286: Implementation of bridge, proxy, and firewall settings in about:preferences#connection

Bug 42299: Unbreak about:preferences#connection when invalid bridge lines are supplied

We switched to a shared bridge line parser. It might throw if an invalid bridge line is passed, but we do not handle the exception in connectionPane.js. As a result, the page breaks.

As a workaround, we can simply ignore the errors, but a better solution would warn the user about that. A bridge card rework is expected to happen in the 13.5 cycle, so I think we can defer a proper fix to that moment. (This should also be the UX of 11.5, 12.0 and 12.5).
