brave have it, but it doesnt look it will, reddit is too smart for that. you need things to spoof you fingerprint, IP address, device and components. im on a forum where they use anti-detect browser(not an actual browser, but to open instances of a browser using different ip/devices,,,etc) to manage all of this, plus you need an reddit account thats not tainted. i think reddit is too used to mozilla already, things adspower, dolphin anty, is one of many that does this.
