I primarily use Firefox, and DuckDuckGo - I occaisionally switch to Google when I need to whip out some boolean search criteria that DuckDuckGo doesn't support.

Anyway -

I'm picking away at some prerequisites for nursing school, so I'm searching obscure academic crap all the time to try to figure what the hell my professors are talking about.

Invariably, my results are absolutely saturated with websites like "chegg" that are basically databases of test questions and answers for students seeking to cheat. The classes I'm taking now are directly applicable to nursing, so I don't want to just float through these ones - I need to really learn this stuff (or rather, my future patients need me to actually know my shit).

I'd like to completely remove chegg and similar websites from ALL of my search results.

I know I can use -"chegg.com" with Google, but there are like 30 similar services and I'd prefer not to type all that in every time I do a search.

Outside of academics, there are plenty of other websites I'd love to never see again too, like quora, anything by Meta, etc.

What'd be a good option to make this happen?
