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.
