Perhaps this bug also affects my problem: after upgraded to Firefox 22 (through the standard Ubuntu update info dialog), my auto proxy config whitelist.pac file is simply ignored! This is highly critical as my children are now able to browse to any website on the internet! Thankfully, I noticed this today as I just migrated one user account from OPera to Firefox.
The only workaround for me is to not use Firefox for the kids. :-( -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1194841 Title: Firefox 22 uses stale manual proxy settings when configured to use system proxy settings, and system proxy settings are set to "None" To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1194841/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
