I need help with Firefox

[NES_Rules]

I've been having this problem for a couple days now. It started with Photobucket when I was using FireFox 2. Whenever I try to upload something by using the "browse" button, the little box comes up and I can browse through the files but as soon as I select a file, the box goes white and then nothing happens. If I try closing out of the box, I get the "program is unresponsive" and I must close it. I've cleared my cache, cookies, private data, restarted FF and my computer but nothing worked. I even upgraded to FireFox 3 but it still won't work.

This happens on every site I try, not just Photobucket.
I've googled the problem and it has happened to quite a few people, but no one seems to have a solution.

When using Internet Explorer, it works fine, so it is FF and not my computer.

Hmm, don't suppose this only started after the last time you updated FF, perhaps a side effect of a security fix (as FF2 still receives security fixes until the end of the year).

[NES_Rules]

It might have, since I'm not sure when I last updated and hadn't tried uploading for a while until the other day.
But wouldn't going to FF3 fix that anyway?

[Cobra]

Hmm, have you tried running Firefox in safemode and seeing if it still happens?

[NES_Rules]

No, I have not. How would I go about trying that?

No, I have not. How would I go about trying that?

Reboot the PC and keep tapping F8 until a list of boot options comes up, then choose Safe Mode with Networking. Log in as an Administrator (Should be a user called "Administrator") then try doing stuff with Firefox.

Thanks  for the help, Cobra and James.
I tried it in safe mode and it worked so I tried it in regular mode and it worked that way too. Now to upload all these scans I've accumulated
