Works excellent to block sites like "pinterest".
But how to block image results?

Freaking finally, I can block out Polygon and other garbage gaming "journalism" sites. Many thanks, it appears to work perfectly.

I was just looking for the filter, but being able to highlight Wikipedia is a huge bonus. 5/5, because it's simple and works exactly as described.

The only small nitpick is that, if searching for a blocked domain (say, RockPaperShotgun), it wastes space to show that domain's search bar, but still filters out the URL portion per usual. With how rare that would happen in normal internet use, it's pretty inconsequential.

Very functional and lightweight extension that does what it is supposed to do. My main goal was to kill off the Pinterest leaches. This was more effective than pouring salt on them!

Use the example code and add your tweaks.

Hint: Wild cards worK! e.g. "pinterest.*"

Good

This addon needs more love! I needed this for an eternity and FINALLY am able to permanently get rid of useless results like pinterest or me.me without having to filter them out manually in each search. I'm really happy now.

Doesn't work. FF 57.0.2 x64 Linux.

Works
