Spyware

very useful!

Stylish is back but is still spyware: https://robertheaton.com/2018/08/16/stylish-is-back-and-you-still-shouldnt-use-it/

Spełnia swoją rolę lecz podczas otwierania odnośników w nowej karcie styl przestaje działać i trzeba odświeżyć stronę aby go ponownie uruchomić.

Spyware SH*T!

It's spyware now.
