I cannot open a New Window. How do I get the ability to open a new (second) window?


When I upgraded from 3.6.15 to 3.6.18 it wiped out the use of all my extensions, add ons, and bookmarks, yet they were all still there. I deleted the suffixes on extensions, rebooted FF and they all started working. The only thing not working is opening a New Window. I click on File - New Window, I right click on FF icon on desktop, icon in Quick menu, I tried dragging a tab to the desktop. Nothing works.

Also FF will not allow me to install the update Adobe plugin.
