Firefox + KDE apps

[Carlos Barros]

HI! Sometime I was googling about Firefox+KPDF and found out that it is
possible to integrate kpdf with firefox. I noticed that firefox can be
integrated with any KDEapp like kaffeine.. Today I have a kaffeine
laucher plugin that works fine, but I'd
like to have make kpdf works if firefox.. Here is a screenshot I've seen:
