We don't support third party extensions, so you need to talk to the developers of xul-ext-notify if you want it to work in Firefox 4. In any case, Firefox already supports libnotify notifications, but it falls back to its own XUL notifications on Ubuntu because notify-osd doesn't support actions. Overriding this would provide an even more sub-optimal experience ("download finished" notifications with no obvious way to access those downloads are completely useless), so it's totally the wrong thing to do.
What should happen is that download progress should be integrated with the launcher in Unity, but that's not for the natty timeframe. ** Changed in: firefox (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/742475 Title: Firefox 4 does not use Ubuntu Notifications -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
