Suddenly Firefox randomly doesn't connect to the internet. I can ping stuff, and I can access sites through Chromium. There was an update through Ubuntu Manager before that, I'm not sure if it had anything to do with it. I restarted just in case, but nothing happened. I went in Error Console:

A lot of "Declaration dropped" items

Actually while I was writing this it connected to my homepage, but as soon I restarted Firefox, the same thing happened. So it connects after about 5 minutes for some reason?

I tried purge and install firefox, but it didn't work.

What happens if you start firefox in safe mode? firefox -safe-mode –  That Brazilian Guy Jul 26 '13 at 14:02
    
I agree with @ruda.almeida - by the look of things from that message, it seems a faulty extension could be the culprit (one of them possibly incompatible with the new version). Safe mode will help diagnose whether this is the case. –  Jez W Jul 26 '13 at 14:10
    
So yeah probably it was a plugin, I think I found the culprit! –  Roy Jul 27 '13 at 10:07
