OK, First let me start by saying I love Firefox and this is the first trouble I have had with it.

I can be browsing the internet, anywhere on any site, and it will freeze saying (Not Responding). When it does this I cannot do anything in the browser or close the browser. It freezes like this every 10 to 15 min and stays frozen for anywhere from 10 seconds to 10 minutes.

I have tried disabling all addons and updating Firefox, adobe reader, and java. When I open my task manager while frozen, Firefox is running at 200,000+ K, and the plugin container at 150,000+ K. I have preformed every system check possible, ran scans with my antivirus and all, the problem is not with my computer or the memory it is the firefox. How can I fix this? Should I uninstall Firefox?

Try a new Firefox Profile.

Un-installing and re-installing Firefox rarely fixes anything, unless you do a clean installation. A new Profile is like 90% of the way toward a clean installation.

Thanks so much @the-edmeister! I did just that and no more freeze! Thank you again, now to migrate my bookmarks selectively.

Insanity that it takes this kind of work to get a browser to function correctly. Is Mozzilla TRYING to ruin Firefox. Every update it's slower and more buggy. Since the last update, it freezes so much, it's basically a worthless browser.

Google the problem, people are jumping to chrome for the exact issue.
