uBlock Origin and uBlock Origin Extra are excellent ad blocking (among a couple of other things) tools for Chromium-based browsers that need them.

There are also a number of browsers, e.g., Brave and Vivaldi, that have heavy duty ad blocking and privacy measures built in to the browser.  Both of those happen to be Chromium-based, but I believe there are a couple that are Firefox-based as well.
