very good very powerful

Pretty mind-blowing. Works on every site even better than Userstyles themes. More people should know about this!

It's a great add on, however, there is no way to adjust the settings for it in my Fennc F-droid browser, based on Firefox, in my Android tablet. Otherwise, I would've given it 5 stars.

saved my eyes, and so my life.
