As for the solution, could defaultPref() be buggy in Firefox? If I test defaultPref() as opposed to pref() using a clean profile, the Ubuntu start page appears instead. If the "Ubuntu Modifications" extension is disabled, the Mozilla start page appears. It seems the default home page isn't being set properly.
This is what happens under Firefox 56.0. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1721965 Title: regression: cannot change home page in Firefox again (Artful) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-mate-settings/+bug/1721965/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
