content-web-blocker 作者： frroossst

This extension blocks content based on keywords, this for some use cases is more helpful than blocking websites as sometimes you might want to block keywords. Especially helpful if you want to block things like adult content.

The extension is simple and lightweight, and since it scans all of the HTML on the website, for your privacy and peace of mind the code is open source, which means you can take a look at it.
