text color does not work when composing an email
When I'm writing a message, I cannot change the color of the text. I'm not sure when this started, I've been able to do it in the past. I'm on a new computer (iMac) but I've migrated Thunderbird following instructions, and have no other issues. When I select some text and try to change the color I get a small window, when I click 'choose a color' I get all kind of palets to choose from (I think this is all MacOS). But when I hit OK nothing happens. There is not even an action that I can undo, so literally nothing happens.
See screenshot attached.
Doe anyone have a clue how to fix this? Thanks!
