How do I turn on black bars on the left, right and bottom of the screen like Tor Browser?
I know that Tor has this thing for fingerprinting and I also want to know If i can turn it on for Firefox because I like how it looks. Is there a way I could turn it on? I heard it's called fingerprinting letterboxing or something.

This is part of the "Resist Fingerprinting" feature.
Note that using Resist Fingerprinting in Firefox has its disadvantages as this can affect the user agent and places you in the UTC timezone and gives you rounded screen dimensions and can give font issues with locally installed fonts and disables site specific zoom. Note that the letterboxing are hidden since 67 (#1407366).
