Works as intended.
I wrote DuckDuckGo results blocker with this extension.
Thanks for your contribution!

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.

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.

Absolutely annoying how it doesn't alert you if you accidentally press the delete button. But other than some other minor things like how it doesn't support reading local files so you don't have type directly or paste your changes to the page, it works pretty well.
