I upgraded recently my firefox browser on my home computer which still runs Windows XP. I can no longer find websites thru firefox, tho, I can load websites through a google or yahoo search. The firefox browser won't download secure or unsecure site. I type in the full name of the site, and it just hangs. I do not receive an error message. Internet explorer continues to work fine on the computer. I emptied my cookies and search history and updated the proxy setting to "no proxy". I still have the same problem. I tried to uninstall and reinstall firefox with the hopes of changing the initial settings (to see if I should have disabled or abled more of the boxes). Unfortunately, the program didn't fully uninstall .. and the firefox reverts to where it was the last time I logged on.
