555904 - Closing tab flips to next-next tab before reverting to next tab

Status: RESOLVED FIXED

(Firefox :: Tabbed Browser, defect)

Description

[Dirkjan Ochtman (:djc)]

I've seen this both on Windows and OS X, most recently with Firefox 3.6.2. When I have multiple tabs open, if I close a tab, the content window switches to a tab that's to the right of the "next" tab (the one to the right of the one I just closed) real quick, before reverting to the correct one.

So with tabs 1, 2, 3, when I close 1, 3 briefly flashes, then 2 shows up.

Can you reproduce this in safe mode?

Comment 2

[Dirkjan Ochtman (:djc)]

I'm now running Fx in safe mode on my work box, I think I saw it once. Problem is, I don't really have a way to reproduce it, although it happens a few times a day.

Comment 3

[Dirkjan Ochtman (:djc)]

This definitely still happens in safe mode, on Windows XP.

Comment 4

[Dão Gottwald [:dao]]

So do you have steps to reproduce?

Comment 5

[Dirkjan Ochtman (:djc)]

No... Do we have a way of tracing/saving open tabs, so that I might be able to look up a specific sequence of tab operations when I see it happening again?

- Start in safe mode (Start/Run, firefox -safe-mode)
- Open the following URLs, in order (I used Ctrl+T, paste into address bar, Enter):

http://techcrunch.com/2010/03/30/unvarnished-a-clean-well-lighted-place-for-defamation/

- Focus on first tab, close (I used Ctrl+W)

When doing this, I get to see the TechCrunch tab for a few tenths of a second before I get to the news.ycombinator.com tab.

I'm seeing this same issue in Fx v3.6.3 on Windows 7.  Closing a tab, when multiple tabs are loaded, occasionally shows next-next tab before jumping back to next tab.  It doesn't matter what tabs are open, just that there are several loaded.  Happens in safe mode too.

[David Bailey]

I've noticed that this bug appears much more frequently when I've got a lot of tabs with pages loaded from wired.com.

This is great stuff. It took me a while to figure out what's going on and what to do about it.

This appears to be a minor polish bug that we wouldn't want to take on the stable branches (beyond the inevitable .1/.2 "cleanup" releases). Is there more going on here than a minor visual glitch that resolves itself?

Comment 18

[Dirkjan Ochtman (:djc)]

No, that's all that's going on. IMO just fixing it 2.0.x is fine.
