Firefox & Mozilla cause lock-ups on a certain website


I'm currently working on a component for Invision Power Board, which I'm developing on my Ubuntu 6.06 laptop with Apache, MySQL and PHP and hosting it. So far I've been using Firefox to test it and it's been working fine up until now. Just recently, though, logging into the test forum has just caused Firefox to lock up my system (even CTRL+ALT+Fx/Backspace don't work). After a few minutes Firefox simply quits and the computer starts responding again. Regular Mozilla elicits a similar response.

Now I know what you're thinking: this kid's been fiddling with the wrong dials or written some infinite loop code or something! But that's not the case; Lynx works fine with the forum, as does Firefox on my Windows desktop when I connect to it from that, and when I comment out the only PHP code that could be causing a problem (i.e. the on-login code) it still crashes. Plus, it seems that logging into phpmyadmin does the same thing now! And yes, I am using the latest version of Firefox and have tried completely removing (including configs) and reinstalling it. I'm using Firefox, which seems to be the latest version available on the repository.

Any ideas?

Invariably when I have encountered that kind of problem it turned out to be Java that was at fault. You probably will find that your user interface is locked up, but if you SSH into the box from some other computer you can work with it, and hence track down the problem.

Try reinstalling/upgrading your java.

Thanks for the suggestion; I tried upgrading Java to, but i'm still getting the crash. An odd thing now is that when I just tried it again it managed to load half of the index page after logging in before crashing, and it only took a few seconds to quit.

Oh, and I'll try the SSH thing in a bit, as I have to set up SSH on both machines.
