IE must be poisoning your other browsers in an attempt for dominance.

Try uninstalling ff completely though. Mine used to crash like that and it fixed when i uninstalled/restarted/installed agian

Wireless broadband connection. And the strange thing is that Google Chrome was working recently.

I could try re-installing Firefox. Will that delete all of my addons? If it does, screw it, I'll wait for the next update.

Kantor:

Your lack of connectivity is due to a system or firewall setting. Try IE8 and see if it has the same problem. If it has the same problem, it's a system setting. If not, it's a firewall setting.

Firefox: Firefox doesn't normally crash for anyone here so it's likely you have plugins that aren't working too well (try disabling them to see if it gets better then re-enable them one at a time) or have some bad temporary data so try clearing your cache and temporary files.

IE explorer is great, never had a problem 10/10

*Runs for the hills*

I would try re-installing anyway. Either that or checking the FF help forums (or whatever they're called). I had a problem with Firefox making every file i downloaded into an empty file, and the help forums fixed it right up.

Firefox has been buggy lately, I was using chrome, but then it's latest update really screwed it up.

I cleared recent history (private data), and disabled some of my newer add-ons. I'll try re-installing it if it crashes again.

Firefox crashes every 15 mins for me. Tried everything, reinstalling, deleting cookies, recovering my PC to an earlier date. I had to switch browsers.

UPDATE: After a brief stint with Opera (great browser, by the way) I decided to reinstall Firefox, and I'm back to using it. It seems to be running faster now, so hopefully it won't crash any more.
