What a wonderful extension!
I suppose it does much more better than stylish not only in the respect of privacy but also the lightweight and powerful design!

Styles are applied when page load is finished, however loading time of page may be long.
If Stylus can run at document start, I don't need to wait page load finished.
Can Stylus run at document start?

updated:
Oh, I find the problem. It is my fault.

I used 'max-width: calc(100vw - var(--scrollbar_vertical_width));' in Stylus.
And the value of '--scrollbar_vertical_width' is set using javascript (Tampermonkey).
i.e. window.addEventListener("load", function() {/* calculate scroll bar size */})

The value is set on loaded, so before loaded the value is invalid and the style will go wrong.
Now I change 'load' to 'DOMContentLoaded', it is fine.

有时候打开一些网页css不起作用，然后刷新一下又好了，问题不经常出现，不过还是希望能够解决。

Been using this for a while. It's easy to find & tweak new styles. ALSO, it doesn't sell your data like "Stylish" does, which makes this extension better in every way.

was working great. But suddenly after the update, all my styles are deleted and new styles get deleted as soon as I install them.

I am currently on FF Nightly on windows and I am not using any "smart" apps like CCleaner that purge extension's storage.

Edit: Not sure what was the actual problem, but after uninstalling and reinstalling the addon, everything seemed to work fine. Reminder: always backup the styles.

Чудесно

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.

Is it possible to use relative paths? If so, how to write them? Thanks

For example, use a picture placed in the /chrome/ folder as a background

Got it, thank you.

works perfectly right from the start and privacy doesn't seem to be an issue

Cool! The best!

All my styles has disappeared just now... can't explain how or why..

Works great, and supports live reload for easily developing in a different editor.

Hats Off to the Stylus plugin developer and the community. Looking forward to a smooth darkness.. ;-)

просто шикарно...все нравится...а ведь я о нем и не знал ...все мучился с етим пришыбленым, чокнутым stylish. всем однозначно советую .

Best CSS editor I've seen so far. Thanks!

My favorite user style extension. Easy to use and lightweight.

Nice tool. Is it possible to add customize javascript code to stylus?

Love it. Used to Stylish over the years and it's a small difference in GUI but it works fine, and probably will work even better after a while.
