We aren’t competing with Tor, we are using Tor as a feature. Brave with Tor does not provide the same level of Privacy as the Tor browser, if your life depends on remaining anonymous, use the Tor browser. If you just want to hide your browsing from ISP, work or school, then tor private tabs are for you. We are just making it super convenient for users to swtich between regular browsing and Tor browsing.
I would encourage use of both!
Note that Private Windows with Tor Connectivity in Brave are just regular private windows that use Tor as a proxy. Brave does NOT implement most of the privacy protections from Tor Browser.
If your personal safety depends on remaining anonymous, we highly recommend using Tor Browser instead of Brave Tor windows.
