Sorry I took so long to get back to you. It took me a while to get back to my system with a suitably powerful enough version of Firefox to verify this. I didn't run into any problems with the game starting up.
No worries, I'll try with no extensions enabled, thank you
Thanks! I had 2 more jams immediately after this jam, so I was a bit burned out, wanted to take a couple days away from everything, etc.
