well ... thanks for the Info.

>From a UX perspective its clumsy, because it occupies space that could
be used, otherwise. I prefer the old approach (warning before maximising
tor-browser). The gray letterbox catches my attention. Maybe a different
color, resizing behaviour (e.g. docking to letter boxes) would do
better. I guess, that other people consider this to be annoying, too.

Clearly, different sizes provide entropy - but for this letter box
(boxes? are there multiple sized ones?) to have an impact, the screen
resolution must be among the few sources of entropy to make a
statistically significant difference. Is it like this? Maybe its an
option to have more letterboxes (e.g. differeing by 10 pixels) to occupy
less space while still reducing entropy.
