Note, this only works with Windows 7. If you had been testing Mozilla Firefox 3.6’s betas, you would know that it had Taskbar/Superbar Previous on it, like on IE 8. Yesterday, I was searching around on about:config, to see if I find something fun to mess around, but instead, I found out the following name: “browser.taskbar.previews.enable”, and it was defined as “false”. So all you do...
