Hello everyone. I'm having little problems with Firefox.. Well, not so little: I can't connect to net with it but I can with everything else. I have allowed firefox in my firewall (comodo) and it's probably allowed in my router firewall too.

So, the thing happened today when I was playing WoW. I was messing with firefox and an addon SwitchProxy at the same time. I tried few proxies but they didn't work, so I switched it off (disabled the proxy, not the whole addon) and wen't to play WoW again.
After few minutes I tried to go to wowwiki to look for macro help and it didn't connect. I tried re-opening Firefox but it didn't help.
Then I thought that maybe I'm trying to somehow connect through proxy and disabled (even deleted) SwitchProxy but it didn't help.´
I tried re-installing Firefox.. I think you can quess if it helped..

Now I can't connect to net with firefox but can with everything else.. (Using IE atm.) I scanned my computer with Nod32 and Spybot S&D but they didn't find anything.
So now I don't know what to do.. Does anyone even have a clue what might be causing this?

PS. I don't think this is anyway related to firefox, but I can't enable Windows Automatic Updates. I have started the needed services (I think) but the updater thing isn't doing anything else than yelling that my Automatic Updates isn't on..

Thank you for your help in advance! I hope someone knows how to fix this.
