Делает свою работу хорошо. Но пользоваться не возможно - слишком сильно замедляет рендеринг любого сайта, словно скорость интернета времен диал-апа.

NICE WORK

I really, really want to love this addon but it it has a single-minded inflexibility that makes it frustrating to use -- or it's hidden its settings well.

- It has Dark and Light options, but no 'leave it alone' which can cause a fair few problems
- It can't be defaulted to a 'do not modify a page unless told to' mode

This causes a lot of extra effort and can hide/mask/confuse conflicts and diagnosis when using other addons like Stylus, etc.

I adore the idea and it does a really great job at what it sets out to do, but it lacks some necessary operational flexibility.

What the heck? Is this the same add-on as https://addons.mozilla.org/en-US/firefox/addon/dark-theme-enhanced/ ? I'm so confused.

very good very powerful

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