I love it, I can change any page to my rules, especially the width

The web is pretty much unusable without this Addon. It's a huge life improvement. It's even encouraged me to learn a bit of CSS just so I can fix minor annoyances that are specific to me. Fantastic.

Нужен для установки RU AdList CSS Fixes.

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.

Since Stylish did stupid things, I appreciate that this addon was released earlier

By the way, as for the question, which is the profile directory or the file where the setting contents of this add-on are saved?

And, to say, I want to use the software called Allway Sync to match the contents of Stylus from any PC

Fluently lets me enjoy blinding white pages again by offering me styles that are dark! Never a problem if you carefully pick the well-maintained userstyles. Thanks for not going the stylish way.

It's like Stylish but it doesn't steal your data!
In all seriousness, it is compatible with all the same styles & I haven't had any bugs or issues with it
