Vertical Tabs: per window

[justsaft]

Ability to enable/disable vertical tabs per window/for each window individually so windows on some screens can use horizontal tabs while on wider screens they can use vertical tabs.

This would be helpful. Also it would be nice if web extension API also allows toggling vertical tab setting.

Vertical tabs are awesome, but not being able to set vertical tabs per window prevents me from using them.

I am waiting for it, and can't wait anymore.
I am programmer who can help voluntary with it, so if you want to give me info.
Furthermore, I need it to work on horizontals monitors and verticals, i used to both of it.

I strongly support this feature.

I frequently use multiple Firefox windows for different purposes. I'd like to use vertical tabs in one window and horizontal tabs in another, while keeping the same Firefox profile, extensions, cookies, and login sessions.

The tab layout should be configurable independently for each window rather than globally for the entire profile.

Please consider adding native per-window tab layout preferences.
