Amazing extension. Works great, code is super simple too: https://github.com/ngc-corp/browser-extension-css-inject/blob/master/inject.js

There seems to be a limit on the number of characters it will save. I don't know what the limit is, but I tried pasting in some CSS that I used on another extension, over 9000 characters, and it wouldn't save it.

Sensacional! Essa extensão é muito melhor do que uma outra igualzinha que tá com 5 estrelas, porém essa é ainda melhor porque o estilo é persistente. A de 5 estrelinhas lá, quando tu atualiza a página já era o estilo. Mandou bem, parabéns e obrigado!
