JavaScript Application error


FireFox is giving me a "JavaScript Application" error. It pops up EVERY time I try to do anything in MTURK.com. I've literally spent hours trying to fix it. Anyone else recognize this problem and can help? I'm not too tech savy, but I tried that SocialFixer thing, and disabling Java, still get the error. It does not error when I have Firefox in Safe Mode, so... any thoughts are appreciated.

What does the error message say?

If Firefox's Safe Mode works well, it could be a conflict with an extension. Could you try disabling ALL nonessential or unrecognized extensions here:

orange Firefox button (or Tools menu) > Add-ons > Extensions category

Usually you will find a link above one of the disabled extensions to restart Firefox if needed. After restarting, any difference?
