1927036 - Vertical tabs sidebar does not auto-scroll to reveal newly created tab from middle-clicking a hyperlink

Status: RESOLVED DUPLICATE of bug 1921951

(Firefox :: Tabbed Browser, defect)

Description

[Jeff Fortin]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:131.0) Gecko/20100101 Firefox/131.0

Steps to reproduce:

1. In about:config, set sidebar.verticalTabs = True
2. Open the sidebar (you may need to add the button for it in the toolbar, as there seems to be no keyboard shortcut for it)
3. Make sure your vertical tabs sidebar is already scrolled to the bottom, and your currently active tab is near the bottom too
4. Middle-click a link in the current page

Actual results:

The newly opened tab (from middle-clicking the link) silently opens in the background, but it is invisible because it is scrolled out, the vertical tabs view does not auto-scroll to it, unlike the horizontal tabs view.

Expected results:

Auto-scroll the vertical tabs view to reveal the newly created tabs as they get created (i.e. match the behavior of the horizontal tabs strip).

Ha! Duplicate detection / search failed me, there already was a ticket about it, bug #1921951.
