i am having trouble browsing the internet on firefox. i have mcafee as a virus scanner & firewall. i am not to sure what i am supposed to do with these to programs to make firefox work. i used to have it installed to my laptop but i stop using it for a while. when i went back to it, it said "server unable to connect" i think i might need directions on how to refresh my firefox completely ( i uninstalled & reinstalled & still having same problem) or directions on how i can get firefox to browse the internet again.
