Plus,[0]Brave is going to block [1]CNAME Cloaking first-party trackers, AFAIK no other browser, not[2]add-on, has or plan to have such blocking capabilities.
I use Vivaldi alongside Chrome for dev, and from that perspective (for the other devs here on HN) they seem like clones of each other. Both running the same JS engine and dev tools.
the [2] link states that ublock origin in firefox already supports this. did you even read it or just copy paste from someone elses brave fanboy comment.
It's basically racketeering.
If you're keen on using chromium with manifest v2 add-ons, Vivaldi and Microsoft edge are both options to keep in mind.
