Since this tool is not opensource I do not recomment to use. Some users claims it has trackers. There is open alternaives (search 'Stylus', etc.)

easy to display

Really great. Simple and easy, tho it's suddenly stopping facebook videos, so I had to disable. (tried many styles and same result)
Any news about a fix for this?

Love how I can have dark themes EVERYWHERE. My eyes are grateful (I'm a developer).

Still not perfect, but getting there! Overall great addon!

Love it!!

Wasn't perfect in the beginning, now I'm satisfied! Great creative app, love the dark themes!

good

Используйте старые версии от 2016 года!!!
Все работает и восстановились старые стили а новый stylish это какой то тихий ужас
Тормозит браузер не сохраняет стили и глючит!

I simply want to change the colour of 'visited links' to RED so that I can easily see which results I have clicked on. A friend showed me a Google result that mentioned this add on being able to help me, but I don't know where to start. I'm 74 years of age and computing is not my strong area. I used to have this ability on my computer, which I seem to have lost since I downloaded the very latest Firefox. I have lost contact with the person who installed it for me.

The new version makes it that much harder to design an idea, make changes, and test them in real time without having to actually reload the webpage multiple times to see what you're doing. Older versions, prior to this Web Extensions rollout, were fantastic for this, allowing me to minimize my impact on server resources while making webpages more accessible to my visual needs.

nice app

Needs to be fixed for FireFox 57
