hi
firstly a fast loading test page ...you must see blue line going up and down in word = ultrasounds
http://www.ultrasounds.com/
2) since you have adobe...maybe its old?
this page will test what you have...assuming you have enable flash in your browser
http://www.adobe.com/products/flash/about/
when I d/load the latest I use the tar.gz from here
http://get.adobe.com/flashplayer/
unpack it and move old flashplayer out of your plugin folder and move the new one
with browser closed...then restart to retest pls.
2) my pathway to a downloaded mozilla firefox (~ iceweasel) is
/home/gordy/firefox305/plugins
notice there is no dot folder pathway which may be your only issue?
of course I have no multiple uses so fox is downloaded to home folder and unpacked there....yours could be
/usr/lib/firefox/plugins/libflashplayer.so
but definately no dots in home folder ok?
