I have downloaded the new update for Firefox 3.6 and now cannot connect to the internet. I've checked my firewall and have uninstalled and reinstalled firefox, but nothing works.

After installing the new update for Firefox 3.6, no matter what I do, I cannot connect to the internet using Firefox. I can get on the internet using my other browsers (Google Chrome and Internet Explorer), so Firefox is the only one that doesn't work. I have already checked my firewall and have added and removed Firefox from my firewall to no avail. I've also already uninstalled and reinstalled Firefox, but so far it hasn't helped.

You may need to remove Firefox from your firewall's programs permission list, let your firewall re-detect the new version, and give Firefox the proper permission(s) to access the internet. See:

I have already tried removing firefox from my firewall. Even when I do that, my firewall doesn't detect firefox and prompt me to add it. And when I manually add it, it still doesn't work anyways. I've already tried the link as well, but it has been unhelpful. :/

I'm not sure if it matters, but a few weeks before this, I did download Microsoft Security Essentials.
