TBB 13.5. How to change letterboxing color back to old black borders like in 13.0.16? Letterboxing color taking over webpage viewport on New Tab

When reporting a bug, please include as many of these as possible:

  • Windows 7 x64
  • TBB 13.5
  • Tor Browser Security Level - Safest but I’ve overriden the default noscript preset.
  • To reproduce the issue,
  1. Install Tor Browser 13.5.
  2. Visit https://example.com.
  3. Notice the new(Horrendous) gradient letterboxing borders.
  4. Letterboxing options in about:preferences has no option to bring back the Dark borders.
  5. I have about:addons > Themes Set to Dark Mode. So the viewport on my new tabs are Dark.
  6. But everytime I Ctrl+T to open a new tab, the new horrendous gradient color takes over the entire viewport for a brief second. This hurts my eyes, as I use dark mode for everything, in a dark room.
  7. The “letterboxing border color taking over the entire viewport whenever I Ctrl+T” used to be an issue even in 13.0.16, but it didn’t bother me as much back then because the letterboxing border color used to be dark, and my new tab is also Dark due to about:addons > Dark Theme.
  • The Tor log - I don’t think the log is required. Do let me know if you need it.

Solution: about:preferences > Letterboxing section must have an option to bring back the old dark borders.

Also please solve the “letterboxing border color taking over the entire viewport for a brief second on new tab(Ctrl +T)” issue. I have to close my eyes every time I open a new tab now, so the new bright gradient color doesn’t flash and hurt my eyes.

Thank you,

This is ongoing, including adding some more UX options

  • this is an issue where a new tab “flashes” the letterboxing color whilst awaiting a the site to load. There is no easy answer here (and it would apply to the letterbox color shown around the sides) as to what color to use, but see below

privacy.resistFingerprinting.letterboxing.gradient is a pref (not exposed in settings yet), to enable/disable the gradient

There is talk (can’t find the issue/link) of adding a UX to set a solid color of the user’s choice - that way if you want it to be dark, or light, or bright barbie pink, that’s up to you


Thank you @thorin that at least turns off the gradient.

Here’s hoping the other issues are resolved before Windows 7 support for TBB ends.
