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.
