Using Windows 7 and Firefox 3.6: I have Firefox pinned to my taskbar, and would like to have some specific sites pinned to the icon's jump list. Is this possible, if so how do I do this?
From what I've read, the developers of a program have to implement jumplist features beyond the basics of opening the program and closing it. You might notice that Internet Explorer has the ability you're talking about.
I guess the team at Mozilla hasn't gotten around to that yet.
In the meantime, you can use Jumplist Extender to add your own things to a jumplist.
The only way I have found is to write an html file with contents like the following:
Change to whatever site you want, and name it something like google.html then
A crappy work around but it works.
