If you have used Firefox the Firefox 3.6 beta, you have probably noticed that Mozilla has introduced support for Windows 7 taskbar thumbnails. Firefox 3.6 allows you to directly select a tab from the taskbar. This is similar to how Internet Explorer 8 behaves in Windows 7. Some people love this behaviour while others find it annoying. I happen to belong to the latter group. I am a heavy multi-tasker and often have dozens of open tabs organised into multiple windows. Taskbar tab previews doesn’t make any distinction between tabs from different windows and is a major productivity bump.
If you find taskbar tab previews irritating, here is a quick way to get rid of them.
- Type about:config in the awesome bar (address bar). Ignore the caution message and proceed.
- Type browser.taskbar.previews.enable in the filter bar.
- Now, you will be displayed a single entry whose current value is True. Double click on the entry to change its value to False.
That’s it. Firefox should instantly stop displaying tab previews in the taskbar.
