Mozilla-plug ins

I keep installing them(flash, mplayer)...but when i go to watch a mplayer plugin one, it just is like loading mplayer plugin then doesn't do anything..and it is still not recognizing my flash plug in...how do if ix this? I have placed both plug ins in both my mozilla folders(mozilla and mozilla-1.4 something)...and they are in the plug in ones.

Did you check to see if the plug-in you downloaded is the one made for your version of mozilla? (Backward compatability is possible, but forward compatability is not... ;(

Here's a page on how to get flash working with Fedora..

now whenever i go to anysite with flash/java it just crashed my mozilla=(.
