uBO or uBOL (lite) will be added eventually to desktop (android hasn’t been discussed) - see harden uBO against fingerprinting (#164) · Issues · The Tor Project / Applications / Mullvad Browser · GitLab (it’s under Mullvad Browser, because there we can harden it to make it fitter for purpose, but once done will be added to TB)
At this stage this is likely to be a 13.5 release
