I've had problems recently with Firefox crashing in the middle of a Live Chess game--it's happened many times.  This is the only time Firefox ever crashes for me.  Is there a known issue with Firefox and Live Chess?

not that i know of, firefox has been by far the most stable for me with livechess, i think its prob an issue at your end mate...

I was using firfox and it was awesome, then it started messing up. I then tried chrome and its working great for now.
