Firefox 10/11 often not responding, scripts taking too long, error log FULL

I use Firefox constantly. I'm now on version 11 but not much has changed. I've been forced to disable most every plugin and extension trying to troubleshoot my issues and I still have the same problems. No matter what site(s) I'm on after 2 or 3 clicks I get the running circle and the browser freezes. If I click again, I get the "Not Responding" message in the top bar. Most of the time it recovers within 30 seconds to 2 minutes and I can continue. Very often the whole thing freezes with no message but before long I get : Script: resource://gre/modules/XPCOMUtils.jsm:331 or Script: resource:///components/nsPrompter.js:466 and neither seems to be attached to any plugin or extension. No matter which version I've used and no matter what site I'm on this happens. I've decreased my allowed scripts to run time to "20" and disabled everything including hardware acceleration. ALSO, about 50% of the time when I'm editing my own site, all of a sudden it becomes VERY sluggish and takes too much time to do anything. When this happens I've switched right over to IE9 and have none of these issues. I also have an error log as long as your arm. Troubleshooting information is below. Please help!

Re: Firefox 10/11 often not responding, scripts taking too long, error log FULL

dom.max_script_run_time = 20 - is the default setting
But that isn't going to cause a "not responding" message due to a slow script.

My advice is to try a new Profile (don't delete your current Profile) and see if there is any improvement.

Thank you so much for your detailed reply. I did exactly what you said and now we'll see how it goes.

I'm going to go ahead and click "Solved" and if I still have trouble I'll re-post but hopefully it won't be necessary. Thanks again! Ron
