It works as expected, I even checked the source code just to be safe. It doesn't make any ajax or fetch requests

I got rid of the thing driving me insane on one site - this worked just as needed, thanks

It is almost perfect except a few UX issues.

Useful. Used it to add "body {overflow-x: hidden}" to a site I use frequently. UI could be nice but it does the job.

Very useful add-on, allows to make ill (re-)designed websites usable again, thank you very much!

does not work

Very helpful, thank you.

Не работает от слова Совсем!

exactly, the plugin I wanna.

Wonderful extension, it was the only one that works for me!

Works exactly as promised! Didn't have any problems so far, really useful add-on!

CSS was applied for a few minutes, but then the plug-in completely stopped working.

Very good solution for customize websites and add missing features, thanks!

It help to fix layout issue on facebook when I use my own font.
