I want to use ublock with whonix.
If I install ublock on torbrowser will it have the same fingerprint as tails?
Because tails had ublock installed on torbrowser.

Probably a good question for the Whonix forum. Whenever I want to use ublock+Tor I usually use a separate Tails computer I keep up to date and running on an OLD Windows laptiop I wouldn’t otherwise use. On rare occasions I have installed ublock on the Whonix Tor browser in a disposible vm, so that it was just a one-off fingerprint.

I will ask in Whonix forum.
I’ll let you know when I know.
