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.

Thank you very much for putting this solution up ! This was so annoying….it was adding an extra step to you clicking on firefox on the taskbar and was very annoying to me..Im sure they had their reasons to adding that feature IMHO its not necessary..why does it make it look like each tab is a page? anyways its back to normal ..thanks very much from Los Angeles
Great !!.. Took me 15 seconds to do … thanks 🙂
Nice! Thanks! Those multiple previews were really annoying me. This solved the problem.
