Status: UNCONFIRMED

(Firefox :: Tabbed Browser, defect)

Description

Attachment: image1.png

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:151.0) Gecko/20100101 Firefox/151.0

Steps to reproduce:

I look at the available launch options for firefox (--private-window and --kiosk)
Then I open a normal private window (Ctrl+Shift+P)

Actual results:

The available tabs (in vertical mode) didn't show up, then I changed them to the normal display mode (horizontal mode) and (see image).
Also some keybindings are messed up by this (Ctrl+Shift+T)?
As well as the Options Button (and others).

Expected results:

1. The tabs should have shown up (vertically listed)
2. turning the tabs to horizontal mode should have been listed horizontally

The Bugbug bot thinks this bug should belong to the 'Firefox::Tabbed Browser' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

NOTE: The only mistake was me not reading the docs and the attached image.

Are you able to share any preferences that have been changed in your profile (you can get them via about:support and you should be able to copy or attach that here) or if you are customizing styling via userChrome.css. This is an usual state to end up in.

In Vertical-Tab mode:

• If you start Firefox with --private-window --kiosk then you can interact with the tool-bar.
• The first screen/tab is completely white, if you open a new tab, then the normal new tab appears.
• (Being unable to close the last tab here).
  in Horizontal-Tab mod:
• A gray-bar appears to the left (removable by pressing Ctrl+Alt+Z)
• You are able to open Bookmarks (Ctrl+B / Ctrl+H), but not able to close it.
• You can close the last tab with (Ctrl+W).

Can you explain how you are launching it firefox? Is it via the command line?
How are you enabling vertical tabs mode once you open the browser? Is that via about:preferences? I suspect there might be an issue with sidebar.revamp which governs the sidebar.verticalTabs pref, as this was disabled in kiosk mode in bug 1948934 but I need to be able to see and recreate exactly what you're doing to verify this.

Could you please share a screencast or list the exact steps to reproduce even if they seem obvious?

What do you see when you go to this website:

https://davidwalsh.name/demo/fullscreen.php

And switch to fullscreen mode?

Kiosk mode is just using web fullscreen mode and when I do it on this website, my vertical tabs go away.

I also tested your exact scenario (on Windows), and I got the private window fullscreen.

Also, FYI, keystrokes are not disabled in kiosk mode (they aren't in any browser)
