Asking here a year later, has there been any progress on determining if switching to Wayland risks creating a unique fingerprint? I’m using the Tor Browser Launcher (installed using APT as recommended) on Ubuntu and the Tor Browser defaults to (Xwayland) X11, which is known to be a serious security issue.
I recently checked and Tails is running the Tor Browser in Wayland (maybe ever since the 5.8 release in December 2022?) but I’m not sure if that means it’s a good idea for everyone else to switch since I heard the Tails Tor Browser may have its own distinct fingerprint due to Tails’ customization, such as installing uBlock Origin.
