evince as internal viewer in Firefox 3.5?

[Joerg Bergmann <email jbergmann de>]

Hello,

in the past, evince was quite good for showing up pdf
documents within Firefox. This has altered, probably with
Firefox 3.5. If the html code includes target="_self", a terribly
old ghostview variant shows up. I have tried to set evince as
the viewer in the application folder inside Firefox settings,
no success. I'm using Fedora 11. Any hints or suggestions?
Thanks!

Joerg
