It seems like each tab shows up as a separate page in Win 7 taskbar preview. When you hoover your mouse cursor over FF in taskbar, a preview shows up that lets you choose which window you want to open. Well, that preview should only show one firefox window, but it shows tabs as separate windows. Very annoying when you have more than 5 tabs open at the same time. Didn't happen in FF 3.5, just this beta version. Reproducible: Always
Duplicate of bug 524742 ?
Viktor, this is a intended feature and something new with Windows 7. It doesn't happen in Firefox 3.5 and only shows one preview because Firefox 3.5 came out before Windows 7 and didn't use the api for the taskbar previews. Firefox 3.6 does for the moment. The next beta or the RC will have this feature disabled by default (due to some bugs) and will be on by default for Firefox 3.7.
