My main reason but also

* want to ensure competition because I'm sure that once it's chromium all the way, we're gonna have a bad time.

Mind you, you can get all that and more in a browser like vivaldi. And that market is.. small. Vivaldi doesn't have to develop a browser engine

The problem is the list keeps shrinking since now Mozilla Corp is an ethically dubious corporation.

Is this even the case? UBO has ~10 million users going by the extension store, Firefox has over 150 million users.

So less than 10% of Firefox installs also have UBO.

* But don't really care about privacy that much

Brave already has an adblocker built into the browser itself and supports vertical tabs.
