Whenever I attempt to access any webpage on the google.com domain, Firefox completely hangs until I exit the program. Gmail is not affected (however mail.google.com is), but google.com, code.google.com and any other hostname on the google.com domain is. I can reliably reproduce this by opening a new tab, typing in a keyword into the search bar at the top of the page and hitting submit. I can also reproduce by opening a new tab, typing "google.com" into the address bar and hitting submit. I can open google.com pages in any other browser on my system (including IE8, Safari 4, Opera 10, and Chrome). I did have a virus a couple of weeks ago (IIRC it was "antivir" - a bogus antivirus program that basically changed my proxy settings to prevent me from accessing the internet and had an in-memory program to block me from opening most programs on my computer). I removed this virus, however, and cannot detect any further traces from it. I only mention it here in case it is relevant. If I restart firefox in "safe mode" I have the same problem. I have disabled any addons I'm not using, and most plugins I have installed are pretty standard. List should be included in the "troubleshooting information" box here.
