Very few working themes, most of them are out of date and either doesnt work or brakes the websites.

I like this plugin, but I want it too in mobile version of Firefox because some websites aren't responsive. Can you create a version for mobiles?

Brilliant, allows me to customize my most visited sites exactly how I want. Most of all it lets me live in my world of Dracula.

None of the instructions for creating the Gmail Classic look match what I am seeing on the screen, so I can not even get started. Uninstalled.

Used Stylish for ages, don't know why I didn't switch sooner. Besides not having the shady past of it's older counterpart, the coding environment is so much nicer, live preview, syntax autocomplete, colour pickers, customisable UI/UX.

I used this to remove rounded edges on YouTube thumbnails (why?) that obscured Thumbnail Rating Bar for YouTube (a different Add-on). Thank you!
