firefox doesn't work on my computer

Posted

To Whom It May Concern:

Hi, my name is Adolfo and I am trying to use Firefox on my laptop running Windows 7. I installed and opened Firefox but it does not open any website. If I run IE or Chrome, the websites work just fine. I had uninstalled and delete Firefox folders from my computer, reinstalled Firefox, check the Windows Firewall and Firefox is allowed thru that firewall, run firefox but it does not get to work. Any suggestions?

Best regards,

Adolfo

Question owner

Thank you. But it doesn't do anything when I type "about:preferences#advanced" in the address bar. It just sits iddled and does not load anything. When I launced Firefox, it doesn't open any web site. If I type a valid website in the address bar, it does not openned it.
