Flashplayer Problems:

Hi..I have Mozilla Firefox as browser.. windows 7

after I installed update a while back my flashplayer  does not work..Ive looked a various

option..ie..activated add ons for firefox etc..  clicked on the icon to install on various sites but to no avail.

when I download and install  the Flashplayer icon disapears immediately from my installed site but looks to be in my downloads.,

Ive tried numerous options but nothing seems to work..  however on oine site I clicked on the icon and it appeard to be ok

until I expaned screen to  'full screen' then it all freezes..
