AdBlock Plus prevents signing in
Description
When I click the "Sign In" button, nothing happens. (The button activates, turning green, but that's it.)
We're on MacOS 10.13.6 and Firefox 74.0 (64-bit).
This is often caused by popup blockers. Can you check if you have one, and if so, whether disabling it fixes the issue?
If that's not it, then it would be helpful if you check the JavaScript console for errors.
You're right. Oddly, it's Ad Block Plus (https://adblockplus.org/) that's causing the problem. Disabling it for code.world fixes the problem.
Is there a way to detect this scenario and inform the user? I don't have Ad Block Plus on Chrome (as I rarely use Chrome), so I don't know if it's the change in plugin or the change in browser that's making the difference.
I don't know how to detect and deal with adblock. This is a dup of https://github.com/google/codeworld/issues/64 and https://github.com/google/codeworld/issues/1075, so this has definitely come up before.
I'll leave this one open, since it has more information, and close that one as the dup
