Regular blank pages when trying to load Discourse forums in Firefox (Android)

Since quite some time I have the issue that Firefox on Android doesn’t load a Discourse forum. I can reproduce this on many different Discourse forums. So I doubt it’s a specific plugin or feature that does this. I’ve reported it to Firefox, but they don’t pick it up.

Can anyone who also experiences this on his/her Android phone report it in the bug report below? Maybe it will get fixed faster that way. Otherwise I’ll just give up on Firefox.
