Awesome addon. With e10s enabled however, custom fonts do not work.

Doesn't work on Firefox Developer Edition Rated 3 out of 5 stars

Been using it for awhile, but I recently switched to Firefox Developer Edition and it doesn't work any more. Even with all other plugins and add-ons disabled.

Rated 5 out of 5 stars

The definitive extension for theming your browser and websites.

What should you use Stylish for, I here you ask?

1) Create a global theme for all websites. Firefox is very limited in this respect, and other extensions rely on GUI to make changes which means you'll lose the level of customization you get with Stylish and end up frustrated when making changes. You'll also find other extensions which offer themes for websites will struggle to apply it during loading, which means if you have a dark theme, you'll be pestered with white flashes during page load.

2) If you're not happy with how your global theme treats a particular website, create an exception for that website, and find/make a theme catered for that site.

See "Advanced matching with regular expressions": https://github.com/JasonBarnabe/stylish/wiki/Applying-styles-to-specific-sites

3) If you're partial to dark themes or backgrounds, you will find yourself annoyed at the white flashing of pages when opening new tabs or websites. Use stylish to change the background color of "about:newtab", "about:blank" and speed dial extensions that will flash white during load regardless of its background color settings.

EDIT: The "edit" button no longer does anything other than open another firefox window (but without showing anything). Weird. I've had to switch to an older version (using 1.4.3).

Really Nice!, A bit heavy on the memory side, but nice overall!

Very Good Rated 5 out of 5 stars

Very good addon. It would be nice to have the option of editing the stylesheet with a preferred editor, not that big of a deal though. Good job

I definitely hate the versions beyond 1.4.2! Rated 2 out of 5 stars

When I write a new style, there is no longer a popping-up window, instead the Stylish window open in a new tab, and if I open it in another window, I have to re-size it all the time, and there is a bunch of extra bars for the tabs, the address bar and the bookmarks just like the rest of the browser inside of this window and I hate it so much!

Also, a lot of things does not seems to work on the new Firefox with it. I used to create some cool designs for the NewTab page and now #newtab-search-container { display: none !important; } for example can not be done. Something stronger for everything in this page is causing it to remains, whatever you do. Same with the UI of Firefox for the favicons and so on. I am not so sure, but it could be due to the new version of Firefox.

And to end with, the version 1.4.3b1 and beyond got what I believe is the auto-complete CSS feature which will auto-type some extra parenthesis, quotes and even do space-tabs for you and I find that really annoying!

Let those things be selective options please.

The options of the new Stylish editor are the same as Firefox's developer tools. If you press F12 then click on the gear icon, options you change there will take effect in Stylish too.

Great addon, easy to use Rated 5 out of 5 stars

Some websites have lots of long interesting texts, but the design makes them very hard to read (tiny font, bad colors etc.) With this addon, I can simply override those websites' CSS with my own styles to make them better readable. Great, thank you!

Use it to get rid of favicons in the bookmark bar Rated 5 out of 5 stars

the bookmark bar is an important part of a browser for me, and one of the most frustrating things about chrome is that it had those fat and ugly favicons in front of each bookmark which took up precious space on the bar. There is no way you can get rid of them in Chrome with an extension or setting of some sort. Somehow I found a simple code to get rid of favicons in Firefox and it work beautifully without any issues. I am not a web developer or anything of the sorts but I really find that this add on worked exactly how I wanted it to. Not to mention that it's been working for almost a few years' worth of updates.

It's amazing! Rated 5 out of 5 stars

Global styles broken Rated 3 out of 5 stars

I'm seeing a lot of global styles (dark) that are no longer working, they jusk blank whatever page it is applied to. I suspect v2.0.2 may have something to do with this.

Rated 5 out of 5 stars

It was quick and easy to use! I'm so glad a CSS counterpart to Greasemonkey exists. Now both of these are on all of my Firefox installations.

This extension is really fun to use, both for importing other people's styles and to just play around making your own. It is also really useful when testing web sites as they are being built.

Great extension. The only thing that I feel could be added to make it better is support for sass. (Pretty please?)
