If you are using recently released Mozilla Firefox 3.6 or 4.0 version, you might have noticed that it supports Taskbar preview thumbnails for each tab in Windows 7, i.e. Firefox shows preview thumbnails for each tab when you hover mouse cursor over its taskbar button as shown in following screenshot:
Some of our readers found it annoying and want to disable this new functionality. So here we are giving step by step procedure to disable Taskbar tab previews in Mozilla Firefox:
1. Open firefox and type about:config in the addressbar and press Enter. It’ll confirm, click on I’ll be careful, I promise! button.
2. Now type taskbar in the Filter box. It’ll show following entries:
browser.taskbar.previews.cachetime
browser.taskbar.previews.enable
browser.taskbar.previews.max
3. The entry "browser.taskbar.previews.enable" would be set to true. Double-click on it or right-click on it and select "Toggle". It'll set its value to false.
4. That's it. Now Firefox will no longer show preview thumbnails for each tab in Taskbar.

wow that is a very cool feature of new firefox. who wants to deactivate that? i wish opera have taskbar tab preview support too but it's ok because my machine can only handle xp :)

wow, this actually helped me to turn the preview tabs on in the new beta 3 LOL
I don't understand why the new beta 3 has by default the taskbar preview tabs disabled. :S

This may not be a good feature for all users.
It significantly slows you down when you're switching between many windows and several tabs in firefox.
