Cannot load my online game to continue working on it since installing latest Firefox update!

Also seems to be a problem playing any game online?

I too am having this problem.

It kinda sucks.

Seems it's not Firefox. Games are working fine on Chrome, but editing hangs on a loading screen. Another argument in favour of using the Desktop version wherever possible, I guess. :|

I have no problem editing games with firefox

Can confirm, everything's working fine now.
