The Graphene docs recommend avoiding Gecko-based browsers like Tor Browser, as these browsers "do not have internal sandboxing on Android." Orbot is an app that can route traffic from any other app on your device through the Tor network, but simply using the Vanadium browser through Orbot is not recommended by the Tor Project .
