Even after I visit several websites, the pinned icon on my Win 7 taskbar for Firefox 21 does not show any visited websites, nor does it show tasks like "Open new tab," or "reopen last session."
I just recently reinstalled, and did see my "bookmark.htm" file in the jumplist under "recent," but no websites have appeared since then. Also, my privacy settings default to "Use custom settings for history," even after I reset them to "remember history."
Let me try that again, with more accuracy.
In your system details I notice this setting:
This relates to your setting for what history to clear when Firefox closes. When you change this setting, it probably switches your Options > Privacy tab from "Remember history" to "Use custom settings". To edit the setting, look for "Clear history when Firefox closes" on that tab.
I wonder whether those settings are affecting what appears on the Windows 7 Jump List?
But that wouldn't explain why your Tasks section is incomplete... do you have New Window and New Private Window?
Note: The Pinned section doesn't show frequently visited sites. Those should appear under Frequent (see example attached).
I know that the Pinned section doesn't show frequently visited sites...I meant "pinned" in the sense of the Firefox icon that's pinned to my taskbar...sorry I wasn't clearer about that.
I don't have either the "New Window," or "New Private Window." I don't have a "Tasks" section at all.
I'll adjust the setting you mentioned, and see if it changes anything.
You're right, I probably read your post too fast. I rarely use the Jump List feature except to launch a new copy of Paint or Notepad, so I haven't had the occasion to research what can "break" the normal display of the list. Hopefully someone with more experience can chime in.
PS...I just checked the setting in question, and it shows as "false."
Maybe toggle it a couple times, either in about:config or using the dialog. There's something odd going on there.

Well, I've checked the setting, and toggled it a few times, like you suggested, and it seems to stick as "false," but I still don't see anything in the jumplist.
As long as we're turning things off and on again, you could try unpinning and re-pinning Firefox on the task bar, per this thread: No Jumplist options on firefox 10.0.2. Hope that works!
