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
