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

Good job
