I have Mac OS
Version of Opera is 69.0.3686.77
After the last update my extensions became dark and practically unreadable. Here's an example of a "google translate" extension (this one is not from Opera, but from Google chrome market)
The backgrounds of extensions become white (like they used to be) only if I change the theme to the light one.
(It wasn't like that in the last update)
pls help
