I just got this computer last Tuesday, and I immediately installed Firefox. It worked perfectly, as it should, with no problems or crashes whatsoever. But, I ended up installing an extension I don't normally use because I wanted to check out how the features worked, and it messed up Firefox a bit... the new tab button was all the way on the right, tiny and kind of broken from the rest of the tab bar. It also installed a "search tabs" thing on the left that, even after uninstalling the add-on, remained there, which was very annoying and also broken/not level with the tab bar. This caused me to uninstall and reinstall Firefox so it would look like it's supposed to. But after reinstalling it, every so often Firefox freezes and says not responding for a couple of seconds. Sometimes it happens every hour, every 20 minutes, or even goes a whole day without it happening. But, it still happens. And also, when I went to update the Adobe Reader web plugin, Firefox froze to the point where I couldn't do anything... the "not responding" thing didn't occur, but it's like when I tried clicking on a tab my computer would ding and not do anything. I don't know what caused this but I know sometimes it happens when it wants you to confirm something or accept security access or something, but there was absolutely no reason to do this. How come Firefox worked perfectly the day I got it, but after reinstalling it the next day because of an error on my part, it acts as if this is the crappiest computer in the world that freezes because of overload?
