Hello! Sorry about the loading problem.
It's likely extensions or browser settings . Change those so things work, and you should be set!
P.S. If this doesn't help--and it's a bit less likely, as you'd have to have the same settings or similar extensions in both browsers--then please send us a url and the code you're submitting so we can check it out. You can skip forward using the Toggle Navigation button (or Table of Contents button) at the top of the challenge, too!
