Stylish is dead , long live Stylus

基本的には良いんですがFirefoxだけこの拡張機能有効にしてると少しパフォーマンスが落ちます
Chromeはパフォーマンスに影響しないのですが。。。

Bye bye stylish.

No-crap addon respecting privacy for adjusting page styles.

Privacy Friendly fork of Stylish browser extension.

Nice useful and privacy preserving

The power of stylish without the ridiculous company that owns it.

easy to use and useful

Completely revolutionized my browsing experience. Dark themes, custom scaling, reordered navigation, accessibility improvements, adding responsive features, removing clutter, etc. This makes it all possible. It's easy to use, too. And the editor does live reloading. And there's tons of styles already. And they can be combined. Oh man, this thing is pretty great.
