You are looking at the Windows Task Bar. What you need to do is open one of the Firefox windows, and see what the tabs are on it.

You might find something more useful at the Mozilla Add-ons Web Page {web link} (There’s a lot of good stuff here) and search for what you want.

Note that this question is about Mac that handles windows differently and also has a keyboard shortcut to cycle though open windows.

I haven't heard of a way to see the tabs in each window in the drop-down list of the Windows menu button.

Does anyone have a response? Or know why even the windows listed in my dropdown list isn't even in alphabetical order? Why does FF make managing open windows and tabs so very, very, cumbersome and difficult?? No other browser is this lame when it comes to that.... Is it really so hard to put them in order, or to add an "Activity Window", which would show all windows and tabs that are open?

Also, WHY DON'T the tabs and windows that open up when I hit Restore Previous Session show up in the HISTORY???? If they did, then I could simply delete all the other history, and I would have a list of all the tabs/windows, so when the number becomes too big, I can simply close them out, and at least have access to a means of re-opening them, As of now, I'm stuck either writing them all down, or one by one saving them as bookmarks (which i really don't want to do), , or who knows what, but again, this is a royal pain, that other browsers make far easier....
