new version Stylish for Firefox 57+ is HORRIBLE... similliar like same Firefox 57

Before webextensions, Stylish for Firefox was awesome. Sytylish for Chrome always sucked compared to Firefox's Stylish and now, since webextensions, Firefox Stylish is just as bad as Chrome Stylish. Webextensions is KILLING Firefox! The so-called "speed increase" isn't there and does NOT justify the GUTTING of Firefox extension functionality!

Firefox Stylish can no longer do real-time CSS updating (must reload/refresh web page EACH and EVERY time!), editing in a window (vs. tab only), and its import feature can only handle so many subsections before it just stops adding them and you must add them manually). Those are my biggest gripes about the webextensions Firefox Stylish, I can no longer continue to use it or Firefox 57+ until this functionality is restored and Mozilla wakes the hell up and realizes webextensions are stupid.

Es muy buena tengo años usándola

Very useful

opens great possibilities to customize your favorite sites as you like it..

super..!!

Me encantan las opciones de personalizacion que da <3
en especial porque tiene muchas cositas rosa (>w<)

Really nice, although of course there are teething problems with the new Quantum version.

One question, which sounds totally silly: how can you use the backup? If I select "Backup all installed", it saves a file, but I have no idea what it's called, or where it is. If I then try to "Retrieve Backup", I don't know what to look for.

The only clue is that the file import says it's either a .BIN or .JSON file, but I have hundreds; thousands of those. Maybe putting the name "Stylish" in the name of whatever file is exported may make it easler to hunt for.

Or, you know, actually tell us what the file is?

Hello! Please, I am having problems to enjoy this extension, already installed, in my Firefox, from a few days to here. I'm with Mozilla Firefox, in this version: (57-0-1-64-bit).
In the upper corner of my browser, the Stylish icon, the following message appears: "An error has occurred using the Stylish database. Would you like to visit a web page with possible solutions?"
Please, to the engineers and technicians of "Stylish", I love this extension, but I'm sad that it stopped working. Can you instruct me so that I can solve this mistake?
Right now, grateful.

Great Add-on! With it I can customize any site: remove ugly annoying banners, hide unwanted (unnecessary or redundant) blocks or images. The web is exactly what I want it to look like.

Great extension.

Since this tool is not opensource I do not recomment to use. Some users claims it has trackers. There is open alternaives (search 'Stylus', etc.)

easy to display

Really great. Simple and easy, tho it's suddenly stopping facebook videos, so I had to disable. (tried many styles and same result)
Any news about a fix for this?
