I was trying to block specific websites via the "hosts" file for Windows- but Firefox would either not load any websites (with too large of a file) or it'd not block all of the websites (with a small file). However, with uBlock Origin I could have a massive blocklist and it'd work flawlessly with no slowness! 10/10. Thank you.

bon bloqueur de pubs merçi à vous bonne jour

Fantastic ad, tracker and content blocker! Can be as plug-and-play or as advanced as you want to make it. Always the one extension I always recommend to everyone

The definitive AdBlocker. First extension I install on any browser.
Default Settings work just fine, and has plenty of customization for advanced users.

I'm a big fan of this content blocker overall, it is very powerful! However, it is actually TOO powerful, and does not turn off when I power it off–it continues to block ads. If this extension could GENUINELY turn on and off, then it would be 5 stars!
