659476 - Alignment guides don't show up when resizing a tab group

Status: RESOLVED WORKSFORME

(Firefox Graveyard :: Panorama, defect)

In Firefox 4.0, when you move or resize a tab group, alignment guidelines appear. The edge of the tab group you're modifying snaps to align with the edge of another tab group, or the edge of the screen.

In the 5.0 beta, the guides show up when moving a tab group, but not when resizing.

Kind of OCD, but it looks like a regression, so I figured I'd report it.

Reproducible: Always

Steps to Reproduce:
1. Go into Panorama.
2. Create two small, empty tab groups. Name them A and B.
3. Position A above and left of the center of the screen.
4. Position B below and right of the center of the screen.
5. Resize A's lower border, dragging it down until it is below B's lower border.


2. Move A past B. Verify that A snaps into alignment with one of B's sides.
3. Resize A such that one of A's edges moves past B. The edge you're dragging does not snap into position.

Actual Results:  
A's lower border smoothly follows the mouse cursor and lands where it is released.

Expected Results:  
When A's lower border comes close to B's lower border, it should "snap" into alignment, and a dashed guiding line should appear.

Not sure how the extra 2. and 3. got in there. Disregard the extra steps.

This works for me (on Linux at least) - can anyone confirm on Mac? Chris, maybe you could provide a short screencast of the issue? Thanks!

The guides also appear when creating a new, empty tab group. However, no guides appear when resizing an existing tab group.

I have followed the video and the resize is stopping at the edge of the empty tab group.

Could you see if the issue occurs if using an empty testing profile? (Don't install any addons into it)

That's strange. I created an empty profile, and the bug's still present for me.

Reporter, does the issue still occurs on the latest Firefox? (Fx5)

Comment 10

[Chris Mounce]

Just tried it in Fx5 with an brand-new, empty profile. The bug is still present.

The alignment is made every time.

Chris, does the bug still exist for you with the latest Nightly?

[Chris Mounce]

Didn't try the nightly, but this is fixed in the latest 6.0 beta.

Considering comment14, can you please change the status of this bug to Resolved Incomplete or Invalid.
