brave promised to continue using v2 so that every brave user would continue having the freedom of choice to use ublock and umatrix if they so desired.

Then there’s also the adblocking brave has built in and also adguard for windows.

Also, firefox is full of tracking and telemetry from advertising spyware now. If you want to use a firefox based browser, use Librewolf instead, all of the best parts of firefox with none of the bullshit firefox has in it now.

Just be sure you enable the letter boxing feature inside of librewolf.
