Works as advertised. It's not only useful for fixing bad css, but also for websites that let you customise your css but lack a preview button.

Works as advertise, I think 1,2,3 starts are just skill issue.

¡SÚPER limpia e intuitiva... me gusta cambiar la letra de las páginas, pero necesitaba un cambio específico no universal en la configuración del navegador.
// LA PANACEA:
* {font-family: Fira Mono;}
MIL GRACIAS!

We cannot have an overview of all css site setup

Worked. Just made the YouTube homepage back to 4 videos per row

it does not work on the website I wanted and on Google either... I tried with the body {
background: #000;
}

does what it says on the tin.

A simple (KISS) tool that helps you do just like it says it'll does. Some stylesheets knowledge helps.

it... works!

Works without any problems! Good stuff!

Simple and fast.

Dark Reader's static option is kinda buggy and slow, CSS Override just works.

Simple and working, if you need overriede for different sites, it is better than better than CustomCSS Injector since you have to keep overrides for all site in same place

Please improve the style editor, grammar highlight and linter maybe

thanks for this addons .thats helps a lot.but i think you might consider adding a manual or some hint how to use this ..because it took me 15 min to figure out that the blank page (style editor of your addons) has suppose to have css code in white space .atleat write a hint that overwritten code goes here..or something like that.

This used to work great, but as of a few months ago seems to have stopped working for most sites... hope the developer can patch this soon!

CSS inject is too late so page is changed after fully load
