Comment 15 for bug 133124

I have also been having the same problem, though mine started very randomly. First off, my firebug plugin just stopped working one day. After a while, if I opened Firefox via the program menu, I would see it show up in the panel and say "Starting Firefox..." and then it would crash, but sometimes it would load, often if I tried opening 2 or more instances, though only one would ever load at a time. Then, I decided to reinstall Firefox and afterwards, it stopped opening at all. This is when I tried opening it through the terminal and noticed the segfault. Now, I recently found out that if I open Firefox by doing a "sudo firefox" it runs perfectly fine! I don't understand it at all, but I just thought I would throw that information out there for anyone who's interested.
