If I open a PDF doc in a new tab and then try and close the tab with ctrl-w it will try and close all tabs unless I switch to another tab and back again.
Running Firefox beta and Adobe Acrobat 10. If I open a PDF document in a new tab, say http://support.avaya.com/css/P8/documents/100146419, and then try and close the tab using ctrl-w, I get the message warning me about closing all tabs. If I switch to another tab and then back to the PDF document and then hit ctrl-w, it will just close that one tab and not all tabs.
Cheers.

I've just been playing around and I set dom.ipc.plugins.enabled to true and now it closes the PDF document but not the tab. I have to do ctrl-w again to close the tab. However, leaving that set to true ruins the scroll mouse functionality as Acroread seems to want it all to itself.
