This add-on is excellent, and very helpful for my photosensitivity! However, recent updates to google docs seem to have broken its functionality a little. Any menus (file, edit, font selection, paragraph spacing) display both the text and the menu background in the same shade of white. Since this text can't be highlighted it is fully unreadable and I have to select from the menus by guesswork alone.

I hate to submit a bug report in a review, but there doesn't seem to be any other possible way to do so.
