When I Right click my browser icon in the taskbar, it has listed 3 items which I cannot delete or unpin. These items are: Open New Tab, Open New Window and Enter Private Browsing. When I Right click on these items, it only comes up with Open. Anything else has an unpin icon on the right side of that item. So, how can I delete the above mentioned items. BTW, my browser is Firefox 4 Beta. OS is Windows 7 Home Premium 64-Bit. I believe they call this Jump lists.
