1955625 - Mouse cursor should not affect ctrl+tab cycling unless it moves

Status: RESOLVED DUPLICATE of bug 1935022

(Firefox :: Keyboard Navigation, defect)

Description

[Mark Reid [:mreid]]

The behaviour of mouse interactions with "Ctrl+Tab cycles through tabs in recently used order" has changed in the past couple of Firefox versions, I think the old behaviour was correct.

Steps to reproduce:

• Enable the pref for Ctrl+Tab cycles through tabs in recently used order in settings
• Open a new window
• Open these 4 links in separate tabs in the above window
  • https://en.wikipedia.org/wiki/A
  • https://en.wikipedia.org/wiki/B
  • https://en.wikipedia.org/wiki/C
  • https://en.wikipedia.org/wiki/D
• hold down ctrl+tab and position your mouse cursor over the 4th tile, leave it in this spot. Do not move the mouse anymore.
• Use ctrl+tab to visit tab A, then tab B, then tab C, then tab D
• hold down ctrl
• press tab once
• wait a few seconds
• release ctrl

Actual behaviour:
Tab A selected.

Expected behaviour:
Tab C selected.

I would only expect the mouse position to override the ctrl+tab selection if the mouse moves after ctrl is pressed down.

If you move the mouse cursor to the bottom of the screen where it doesn't overlap with the tab previews, it behaves as expected.

Also note that if I cycle tabs very quickly (before the tab previews show up), it behaves as expected.

This should be fixed in 137.
