My firefox hung in a weird way and I think it might be because of this. However what happended was slightly amusing.
I was in the middle of a chess game. I played a move and the opponent's clock just seemed to be ticking down. The correct response for them was obvious so I couldn't understand why they were taking so long. Eventually I became suspicious and realised all my firefox tabs were kind of "stuck" and I couldn't refresh anything etc. Eventually my opponents clock seemed to run out completely but the game didn't end. I had to forcefully restart my firefox and when I got back to my game (fully expecting to have lost on time) saw that my opponent had played a terrible blunder and immediately resigned.
