You can add it to "My filters" within uO. Host file has no wildcard support which you need for full coverage.

what is uO? I've been using a hosts file. I'd love to up my game.

Ahhh... other comments are saying https://en.wikipedia.org/wiki/UBlock_Origin

Tangentially related, the author of that project has also created uMatrix. Well, it's the micro symbol, but you get the idea.

uMatrix is pretty much like an old school software firewall, except it is just for your browser. It works by whitelisting, instead of blacklisting. There is a bit of a learning curve, but after you've visited your most visited sites, it becomes a fairly easy solution. As you fist visit sites, you configure it to only allow what is needed to get the functionality you want. Once done, you don't generally have to muck with it further.

As stated, there is a learning curve. There are many choices of what to allow and block, but you can surely figure it out. You can even export and share your configuration.

I am not affiliated. There is a version for Firefox, Chrome, and my beloved Opera. It'll probably work in Pale Moon, Vivaldi, etc...

It eliminates the need for multiple extensions. I've been very happy with it.
