I can't find the preview button!
Do i have to save it to test it?

Working fine on 58 nightly build!

It is great, all the styles are compatible and new firefox is supported, thank you!

Espectacular complemento que se hace indispensable para arreglar sitios que fueron pensados para verse en un monitor con una resolución de 1024x768.

We just want to thank the dev(s) here for their excellent support in resolving our issue with getting Stylus to accept and run a particular theme we had been using in Stylish for a long, long time, but wouldn't initially work in Stylus in our preparation for Firefox 57+!

Superb job, thanks!

Not just an alternative to Stylish but an improvement.

GOODGOODGOOD

I'm using Ubuntu 16.04.3 with firefox when I used this extension and I must say that this works very well, unlike stylish which doesn't do pretty much anything other than being a bit of a bloatware.

This extension is a must have!

I mainly use Stylish to set a dark them on websites, to prevent my eyes bleeding.

Does what it's supposed to. Performance seems good. Unfortunately cannot be used in privileged URLs like "about:home" but that is a Firefox WebExtensions restriction, not the fault of the add-on.

All I could ask for:
It themes websites properly, works flawlessly on the latest nightly and doesn't get in your way while doing its job.

I'm using FF beta channel (56b11), it says "in this version of Firefox: chrome.extension.getBackgroundPage() doesn't return a valid result", which makes it unuseable.

just about the PERFECT replacement for nightly. THANK YOU

Finally an good replacement for Stylish! Thanks!

It works very well for basic needs with one exception. Styles on side panel pages do not work.

The tool is well done and works fine.
Thanks.

Haven't had any problems with it.

The only downside is the lack of a simple whitelist into the global themes, people have to know some programming in order to use it. The interface of this addon needs a nice work but even with that, it's a fantastic job. Thanks for the addon.

To all f-face who ran into trouble running this add-on, why don't you guys send a report to dev, instead of whining and giving bad reviews just because you have a shitty ass configuration.

keep up!

Fix it, please :(

很棒的应用，谢谢

I am having trouble adding styles on userstyles. It worked before but not anymore. The add to stylus popup shows and then the style is not added the userstyles are empty after adding. I have tried a few styles with the same result.

Adding styles more manually by copying the userstyle code and saving it does work. Have userstyles found a way to stop Stylus from adding styles easily? Their site is very difficult to navigate not allowing right click and opening styles in new tabs, attempting to stop copy unless the keyboard is used.

Unfortunately even after adding manually I cannot find the style in the installed styles screen. The only way I have of knowing that a style is installed is by the number that now shows on the Stylus button when I visit the site that the style sheet applies to. It did not do that before when I confirmed to install the stylesheet from userstyles.

[EDIT] Strangely, if I click on the style, which I manually installed, shown in the drop down list shown under the Stylus button while the installed styles page is open the style then appears on the installed styles page. Surely this is a bug? It should show after being installed.

Unfortunately all this makes it far more difficult to use.

[EDIT2] After more testing, I disabled Greasemonkey and FEBE and after a restart Stylus then worked. However after re-enabling those two extensions Stylus now works and can install userstyles from the website. They are also showing where they should do. I am not sure why this happened but I am glad to say it is now working okay.

why do the hell i cannot export style from android version

Best, better than stylish and compatible with the latest firefox nightly!
