It works wonderfully for my own purposes, but the editor seems to incapable of understanding the @moz-document function and as such I cannot publish my styles to the website. The tutorial in the FAQ to "fix" this error does not seem to be up to date with the extension and does not produce usable code. Disappointing, as this extension has so much potential in a day and age when websites all look the same and provide few customization options.

Отличное расширение полностью соотсвествует описанию +имеет открытый исходный код блягодаря чему можно не беспокоиться за свои данные)

good

I only use it on a couple of websites, but it really makes visiting them more enjoyable.

Thank you so much for this add-on: With this add-on I could change the colour of visited links in firefox. All other things didn't worked (like userContent.css etc).
