firstly a fast loading test page ...you must see blue line going up and down in word = ultrasounds
2) since you have adobe...maybe its old?
this page will test what you have...assuming you have enable flash in your browser
when I d/load the latest I use the tar.gz from here
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
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
but definately no dots in home folder ok?
