For several days my computer has randomly frozen solid while browsing in Firefox. I thought at first it was video related, but when it froze up when no video was playing, and I had updated everything I could update, turned of hardware acceleration, checked for malware, etc., I finally decided that the problem is with Firefox. It has only frozen when in Firefox. It freezes so badly that I have to force a shutdown because even ctrl-alt-delete doesn't work. So, I opened IE long enough to search for information about browsers and opted for Opera. It's different, but so far I like it. Even my videos are playing better in Opera. So far it hasn't frozen. If it does, I will then have to assume that the problem in in my computer, not Firefox.
