@ Celdrøn:

Yes I do. And: I admit I may be one update behind.

But: Firefox does not do the syntax highlighting, it's CSS, and the ugly message is part of the Fandom editor box. Nonetheless, I will install the last Firefox update and see if that changes anything.

You seem to know more about Firefox incompatibilities, so what's going on there?

(Besides, AnimePerson1 had the same issue with Chrome.)
