Brilliant Rated 5 out of 5 stars
Signed up just to write down this reply: excellent, very flexible tool to make websites look like you want. The way it used to be in oldschool browsers like Opera.
Excelente. Rated 5 out of 5 stars
El único problema es que hace que el navegador tarde en iniciar.
Excellent! Rated 5 out of 5 stars
Don't bother with yazzoo7 'ratings' below, it appears s/he can't find the way out of a paper bag. Stylish works and supported very well ( https://forum.userstyles.org/discussion/47693/stylish-for-firefox-2-0-3b1#latest ). It's a must have extension if you write/edit styles: to change how your browser looks or to change a web page. It's easier to use than userChrome.css or userContent.css 'cause you can preview changes (or a style you're about to install) without restart. The forum is very helpful and there's plenty of helpful documentation to get you started to write own styles if you can't find what you're looking for among thousands of all-ready styles.
To export styles, use Stylish Editor Mode button to save a style to a file. Then install a style from that location into a new profile by double clicking the the file name, as usual.

Must have Rated 5 out of 5 stars
Even if you don't need to customize any website styles, at least you can set @font-face rules to substitute fonts which you don't like once for all.
Good add-on, missing a few features to be Great Rated 4 out of 5 stars
Installed the add-on at home added a few styles and customized them. When I got to work the add-on was installed but none of the styles. I looked at exporting the styles I had an importing them but that feature didn't exist either.
Once styles sync or even a simple export/import function is implemented this would go to a 5 star.
Very Good! Rated 5 out of 5 stars
The only thing is missing is the sync feature.
Stopped Working Rated 3 out of 5 stars
I really love this how it takes all where bright white pages and brings them to a dark mode!!! I really miss it...it stopped working when I jumped from FF 39 to 41. Which I regrer doing now.
Any fixes coming soon?

Works as expected, would love to see it work over Firefox sync like GreaseMonkey.

Geniales Addon - macht häßliche Seiten schick Rated 5 out of 5 stars
Genial umgesetzt: man kann einfach auf einer Seite sagen "Style für diese Seite erstellen" und dann mit ein paar CSS befehlen die Seite verschönern.
Schön wäre noch, wenn man bestimmte Bereiche mit CSS-ids versehen könnte um Elemente anzupassen, die sonst nicht eindeutig anzusprechen sind
It would be nice if you could additionally define certain areas and provide them with user-defined CSS-IDs so you can match elements that are otherwise not clearly addressable with only CSS
Problem Rated 5 out of 5 stars
I'm using linux and before updating firefox, this extension worked properly but after that I can't apply individual themes(one theme in one time)
I can only apply the theme by the "Turn all styles on" option
Other than that, this extension is an eye saver
Use this and Greasemonkey Rated 5 out of 5 stars
And take the web by the horns!This user has a previous review of this add-on.

I can't import from local .css files from my computer/mobile. :(
Rated 3 out of 5 stars
It worked just fine on my other computer, I could even synchronize my styles on any computer with things like dropbox.
Now I always have a problem when starting firefox : "Stylish is having problems opening its database. It will be non functionnal until the problem is fixed"...
It tried to compact the db with db sqlite browser, but did not fix the problem.
I uninstalled and reinstalled it but still can't solve the problem.
Whenever I install/create a style, it disappears when I restart firefox :/

What did you do to the edit box? I can't use this. Why do I ever update anything?
It just works Rated 5 out of 5 stars
Good enough for me
Rated 5 out of 5 stars
This addon is fantastic! I can't believe that before I installed it I could manage without it. Works like a charm.
Como es que aun no se puede editar cuando se quiere instalar? Rated 2 out of 5 stars
Veo muy estupido que no posea la opcion de poder editar un estilo antes de instalarlo, existen problemas de compatibilidad que se deben solucionar antes, arruinan cosas tan sencillas
