I've just been hit by this today, I don't recall upgrading Firefox today but I presume I must have. I don't have the libnss3-0d package installed, so it's not that.
I did have Firefox open and it stopped opening links from external applications (Xchat & Evolution) in new tabs, so I closed it and attempted to start it again to see if that would help - at this point it didn't re-load. When I tried to run it from the command line I got this: de...@serenity ~ $ firefox-3.5 Couldn't load XPCOM. de...@serenity ~ $ Any suggestions, or requests for more info? I can still run firefox (3.0) by the way, and the rest of my system seems fine so far. -- firefox gives "Couldn't load XPCOM." and does not start https://bugs.launchpad.net/bugs/436190 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
