User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6 Build Identifier: Firefox 3.6 This is really a new feature in Windows 7 called Aero Peak. Whenever I open multiple tabs in Firefox and I point my mouse arrow towards the Firefox pin on the task bar, I can't preview the tabs/web pages I have currently opened. Whenever I want to see my opened tabs through aero peak, I literally have to just click and open multiple Firefox windows instead of tabs. The other thing is whenever I open multiple windows of Firefox though, I can preview through aero peak all at once which is inconvenient. For example, in internet explorer 8, I can preview all the tabs I have opened from the task bar as I simply just hover my mouse towards the Firefox pin on the task bar and aero peak it all at once. I wish I could upload a sample picture I am talking about. And one last thing is, I don't see any jumplist history when I right click on the Firefox Pin on task bar. Reproducible: Always

Oh, and there's nothing about this bug that is security-sensitive, so please don't check that box because it means fewer people can see it.
