1) How long has it been this way?
I'm not sure. I just tried yesterday and today and it wouldn't work. >.<
2) Has zOMG ever worked in the past?~
3) How about gaia's other games, like towns, rally, etc?~
I haven't tried them but I'll go do that now.
4) What is the name of your internet service provider?~
Brighthouse. I think it's a Florida thing...
I just tried to on IE instead of Firefox and it loads...
Well, good to hear it works~
That said, if you want it to work on Firefox, try clearing your browser's cache (Tools > Clear Recent History > Everything). Then, go here and delete anything with "gaiaonline" in it. Navigate away from that page to save the settings~
After all that, maybe zOMG will work on Firefox again? If it hasn't already of course~
...Oh right, you could try updating your flash player version too, unless you had recently done that~
