[ER] Suggestions to make letterboxing more friendly/usable #2759

Hello, I tried using letterboxing but unfortunately I can't make it feel right to me. So I wanted to suggest adding a few options which I think would make it more friendly. Not sure if it matters much but I'll mention it when Mullvad has the option.

• center the letterbox vertically in the window (Mullvad offers a setting for this)
• reuse the last window size when opening a new window / relaunching the app (Mullvad offers a setting for this)
• set a distinct background color that appears outside of the letterbox + border color around the letterboxed content

Actually, reusing the last window size may be just broken on macOS? It seems like it is reusing the last window size when testing on Linux.

I think you shouldn't even use letterboxing at all, it's not necessary. Because it makes you even more unique and stand out. You can test it for yourself. Go on CoverYourTracks site, make Librewolf fullscreen, enable RFP, enable letterboxing. Now test and look at the "one in x" metric. Note it. Now, make Librewolf windowed, with either letterboxing enabled or disabled, it doesn't matter, but with rfp. You'll see it'll make you less unique. So that's generally better - using the browser in windowed mode instead of relying on letterboxing which makes you even more unique in fullscreen.

Oh now I'm confused, I thought letterboxing would put more people together into the same size steps and therefore make them less unique. The initial reason I enabled letterboxing is because I wanted LibreWolf to always reuse the last window size, and I thought letterboxing would help privacy in that case.

You don't seem to be making much sense here...?
