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

我不能在我的Andorid设备上使用了，希望提供Android版

I only just found out how horrific Stylish is for data privacy, and I'm very glad y'all maintain this fork that doesn't exfiltrate all my browser data.

hello, what I missing is only cloud backup [dropbox etc.] ... option to export to local files only is obsolete

There are a lot of great things to be said said about this wonderful add-on. It's one of the best add-ons out there; really well documented, easy to work with and even easier to use.

Lo más parecido a Stylish que hay, pero le falta un mundo para llegar. Estéticamente deja muchísimo que desear, es mejorable en todos los aspectos. La ventana modal que aparece en las notificaciones tiembla a causa del scroll vertical con el ratón, además la página de edición de plantillas es horrenda. A nivel funcional, eso sí, funciona bien.

A great open-source solution to replace the now rogue Stylish. Stylus is a WebExtension so it won't change Fierfox itself.

I actually like it better than Stylish. I have not encounterd a single glitch with either styles or responsiveness like I did with Stylish, on occasion.

Stylus is also a a great way to learn about editing and creating Cascading Style Sheets (CSS).
