This could be a problem with your firefox profile. Try running firefox in Safe Mode and see if that helps. If it does help, consider making a new profile.

My problem is solved by downgrading to 6.0.1. I noticed Firefox 6.0.2 freezes (not responding) a lot. Then one day I used my old laptop (using 6.0.1) and it runs perfectly. Right now I am using 6.0.1 for more than two hours and not yet encounter any errors. xD

I would recommended you saved all favorites and addons list prior to downgrading. Before downgrading, uninstall current firefox and check box that remove everything to prevent reoccurring problem.

Hope this help you all. google firefox 6.0.1 download and you should be able to find some links. mozilla/firefox doesn't have 6.0.1 for download, so don't bother searching it on mozilla.com.

Thank you. I'll give it a try. Really don't want to go back to IE.

Matt2 - this is NOT a profile issue! It is a Firefox 6.0.2 issue.

As a temporary get around, dare I say it? I'm using Google Chrome which doesn't have this glitch in it. Been doing so for a couple of days now and no problems at all. I've gone back to Firefox a few times and the two or three second freeze every 10 or 15 seconds resumes, so I'll maybe check Firefox in a few months and see if there is any improvement. Or maybe, I'll be so used to Chrome by then I won't bother.

Hope this suggestion helps.
