Не работает автодобор.

The addon is great to change the appearance of a website, however, it seems it canNOT be used with VK. If either Stylus or Stylish (it doesn't matter, I tried) is on, VK page elements, be it the messenger or literally any other page, either move up and away from the view, or the browser shows the page with no CSS or HTML formatting active, just plain text. This only happens on Firefox, too, on all Chromium-based browsers, VK works fine with both Stylish and Stylus. It also doesn't matter if a VK-specific style is active or not, the pages break even with no styles active. This addon breaks only VK pages, all other websites work as they should.

Stylish site never loads. Just a spinning color wheel forever. It's not Stylus's fault, but since it's an integral piece of what this add on does, it's just not that useful anymore.

感觉还行，就是不会用

when i want to open editor in a new window-it does not show !!! I only get the name in the taskbar but with no window and no style...please fix it or help me .

Sadly, Stylus (without having any styles loaded) messed up my zimbra-webmail and I cannot use it anymore.
Other than that I was generally happy with it. Silently pushing DOM-manipulation is not appreciated, however.

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。。。

Need to be able to easily make rules for sites. For example, I can't set it to use a theme globally but then disable that theme and/or use another one on specific sites. I've yet to find a theme that looks good everywhere, so the ability to customize per domain, and even per page, is a necessity.

UI is very poor in Firefox Quantum
