"evince plugin" in Firefox - F11, how?

view full story

http://forums.fedoraforum.org – I remember in Fedora 10 I managed to get Firefox open Evince within its window whenever I opened a filetype supported by it. IIRC I think it was done through mozplugger (the generic mozilla plugin). I tried to get the same in Fedora 11 and Firefox 3.5... Could it be possible to have the same behaviour in Fedora 11 with FF and Evince? I wish I had a screenshot of Evince working inside Firefox, with all and even windows which displayed a framed webpage, alas I do not. However, I do know it is possible in Fedora 10. (HowTos)
