I have been on the computer several times today. Firefox is my default browser. When I have logged into Facebook, I can't post (I can type something but it won't post), comment on a post, like anything...even 'poke back'.

I click the mouse and absolutely nothing happens.

Internet Explorer - all works great except there are all those ads which I have blocked in Firefox.

Anyone know why this might happen? Google is being no help at all.

Thanks!
