Firefox 3 immediately crashes when started

[Morgan19]

I'm currently running OSX (10.4.11) and have been using Firefox 2 for a while now. I finally got around to downloading and installing Firefox 3, but when I try and start it up it crashes with this error:

Can anyone help decipher what's going on, or possible fixes?

Understand millions of users on numerous platforms[—Mac, Windows, Linux—]happily use Firefox 3.5.7 everyday without a problem. The problem is likely something unique to your system. The fact that you held onto Firefox 2 for an eternity does nothing to explain why Firefox 3 crashes. What would be useful is to know which websites trigger your crashes.

You could also do a few things:

1. Repair permissions and restart your comp (this fixes 80% of issues on a mac)
2. Disable all Add ons, maybe one of them is crashing your FF?
3. http://www.mozilla.com/en-US/firefox...uirements.html
Looks like your computer probably satisfies the system requirements. You might consider deleting any old references to Firefox (v.2 preference files, etc.)
