Description of problem:
Many of my RSS feeds include flash plugins. Up until recently, those flash
plugins worked fine in Liferea. If I read a feed with flash plugins the flash
plugin would display within Liferea.

It seems about the time the the Firefox 3 updated came out they stopped working
in Liferea. They still work fine in Firefox. 

This is using the Adobe version of the flash plugin. 


Version-Release number of selected component (if applicable):
liferea-1.4.15-5.fc9.i386

How reproducible: 
Every time

Steps to Reproduce:
1. Read a feed that includes flash plugins
2.
3.
  
Actual results:
Popup appears saying that you're missing a plugin and asking if you want to
install it. Hitting yes, doesn't seem to do anything.


Expected results:
Best answer the flash plugin would be embedded.
Second best answer, the popup appears and hitting yes would install the flash
plugin and it would work next time.
Third best answer it would ask once about installing the plugin, fail to do so,
but don't ask again until Liferea restarts, because having it popup every time
an article in a feed includes flash is annoying.
