This must be a known issue, but I don't see recent messages that appear to be about this problem with firefox.
Over the last few updates I'm unable to run firefox at all. If called from cmdline I see: firefox Couldn't load XPCOM. I read somewhere it might have something to do with Xulrunner. But I see my latest update also updated xulrunner. Now running these: Sat Aug 1 11:45:01 2009 >>> net-libs/xulrunner-1.9.1.1-r1 Sat Aug 1 11:48:15 2009 >>> www-client/mozilla-firefox-3.5.1-r1 Anyone have a tip about this?
