Support for 'Fastmail' themes.

Post by Spudozo » 2020-11-04, 11:16


Not the end of the world but I cannot alter themes anymore in Fastmail and they say:

"Unfortunately, your browser doesn't support the technologies we now use to add theme support,
specifically CSS custom properties and JavaScript dynamic import"

I note that there is a userchrome.css hack (is that the correct terminology?).
Would this solve the issue assuming I can undertake such a daunting task? :)
