A privacy bug in the Brave Browser caused the leak of the Tor onion URL addresses visited in the Tor mode by the users. The privacy bug resides in the internal ad blocker component of the Brave web browser. The fix will be released to the stable version with the next Brave browser update. Brave users can access onion sites inside Brave private browsing windows with Tor’s Tor mode. Brave doesnt connect directly to a website, instead, it connects to a chain of three different computers in the the Tor network.”]
