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 still see this occasionally.
I had reported this in another bug report. Same problem
Mozilla/5.0 (Windows NT 6.1; rv:2.0b6) Gecko/20100101 Firefox/4.0b6
I'm seeing this issue as well using Minefield (4.0b8pre). Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:2.0b8pre) Gecko/20101013 Firefox/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 (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.
