I do not know Brave.
Instead, I use the Mullvad browser, which is based on Tor Browser, but without using the Tor network. I configured this afterwards, because I want to continue surfing with Tor.
Now you might ask, what's the point? The difference is that the Tor browser changes IP addresses very quickly, while in the configuration I use, the change is slower, as far as I have observed correctly. The difference becomes visible with RVF. With the Tor browser, every other page is an "Oops, your IP address is blocked" and I have to request a new IP, which can be quite annoying. The cause is the hosting, because Cloudflare doesn't like Tor browsers, at least in this case.
But thanks to the admins of this forum, it is not hosted by Cloudflare and the Tor browser runs here without problems.
But as Thefinalepic already noted, a browser configured to access the Tor network is not the same as the Tor browser. There is probably some difference here that I can't name yet.
