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'm having problems reproducing this problem, but I to see other TabCandy and tab preview integration issues I will file.
I had reported this in another bug report.
Same problem

I'm seeing this issue as well using Minefield (4.0b8pre).

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 ( and is now the world's most common operating system, it'd be good to have the live previews working properly.
