I downloaded version 3.6.12 and now Firefox can't connect to websites

more options

I had version 3.6.9 installed, then I downloaded version 3.6.12 and now Firefox can't connect to websites. It says "Unable to connect." I followed all the instructions on the help page about checking my firewall and removing then re-adding Firefox to the list of safe programs, but it still won't work. Is there any way I can re-download version 3.6.9? Or does anyone know what else I can try?

I found my problem. I had an expired version of Norton Internet Security that didn't uninstall properly, but I was able to remove it with the Norton Removal Tool and now Firefox works.
