1731861 - Tab bar scroll position not remembered when closing FF

Status: NEW

(Firefox :: Tabbed Browser, enhancement)

Description

[daniel.schaaaf]

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:93.0) Gecko/20100101 Firefox/93.0

Steps to reproduce:

This bug is probably related to bug 1719532. Firefox not remembering the tab bar position is not the worst issue I can imagine, but it can be very annoying. Especially since Firefox is so stable and memory efficient that having many tabs open does not affect system performance the least :-)

Steps to reproduce:

Open twice as many tabs as the tab bar can show.
Scroll the tab bar with the right side arrowhead all the way to the right.
Activate a tab a few tabs to the left of the rightmost tab.

|<|tab30|tab31|active_tab|tab33|tab34|tab35|tab36|>|

Close Firefox and start it again.

Actual results:

After startup, the tab bar will have been scrolled to the left, so that the active tab is now the rightmost tab.

|<|tab26|tab27|tab28|tab29|tab30|tab31|active_tab|>|

Expected results:

The tab bar should not scroll to align the active tab to the right side.

|<|tab30|tab31|active_tab|tab33|tab34|tab35|tab36|>|
