[Samuel]

User-Agent:       Mozilla/5.0 (Windows NT 6.1; rv:2.0b4) Gecko/20100818 Firefox/4.0b4
Build Identifier: Mozilla/5.0 (Windows NT 6.1; rv:2.0b4) Gecko/20100818 Firefox/4.0b4

When looking at task bar thumbnails it shows tabs that I used to have, but have been closed out. When they are moused over a blank window with a small black square in the top left corner appears. These bad task bar thumbnails tabs cannot be clicked off by the x on the task bar thumbnail.

Reproducible: Sometimes

Steps to Reproduce:
1.Have Firefox open a long time with computer.
2.Open lots of tabs.
3.Close some of the tabs.
4.(sometimes) Letting computer go to sleep.
Actual Results:  
When this is done then some of the tabs still show up in the task bar thumbnails.

Expected Results:  
It should have deleted them.

I have a bad feeling that this is a tabcandy regression. I did see this from time to time after it landed but have not in recent builds. Can you confirm this on a more recent build?

This is on Firefox beta 4.o build 4.

Yes, I am suggesting that it may have been fixed in the upcoming beta 5 or one of the nightly builds since the beta 4 build.

I started having this issue with FF 6 beta 5. Windows 7 x64.

Fixed this issue by disabling task bar thumbnails and re-enabling.

This bug is still an issue.  There's no 'fix' other than restarting Firefox each time.

Now that Windows 7 has overtaken XP (http://gs.statcounter.com/#os-ww-monthly-200910-201110) and is now the world's most common operating system, it'd be good to have the live previews working properly.
