Firefox won't open after close.

Every time I close firefox it won't open back up. I kept deleting the old profile and it'd load up once and then after I closed it again it stopped working. I have narrowed the problem down. If I delete xpti.dat and compreg.dat it will start just fine, for one time. I am planning on making a sh script to do that automatically, but would still like to know why this is happening.

Hello Christopher.

Hopefully this support article is what you need:

http://support.mozilla.com/en-US/kb/Firefox+hangs

In any case, it's possible that you are having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?

Whenever you have a problem with Firefox, whatever it is, you should make sure it's not caused by one (or more than one) of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in safe mode (don't forget to select Disable all add-ons when you start safe mode). If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See this article for information about troubleshooting extensions and theme and this one for plugins.

If you need support for one of your add-ons, you'll have to contact its author.

I added

rm ~/.mozilla/firefox/u0xcemct.default/compreg.dat rm ~/.mozilla/firefox/u0xcemct.default/xpti.dat

In the shell script that executes firefox. It automatically removes the two files that seem to be prventing firefox from opening. I haven't had any problems since.
