Works alright, but to this day there is no way for users to contribute their own styles. As such, most available styles are often outdated, and I have to fix them or write them myself.

I have lost all my custom styles after the last firefox update, it seems like the addon folder structure has changed, is there any way to get my styles back?

Will never go back to Stylish. Thanks for your offering. You guys should seriously consider creating your own repository and drive traffic away from userstyles as it's a trash website.
