Is something wrong with adobe flash and firefox?

So...  Everything was working fine up until a few days ago.  Youtube works fine, but that's because it runs in the HTML line.  But as for videos and sites where you need the flash player to work... nothing.  Now I've read and tried about everything from completely uninstalling and reinstalling, to resetting firefox, to changing values, to ugh... everything.  Problem is... when I went to the test site, it said click on the icon below.  It would show if flash was working, and if it wasn't, there would be a box where I could still right click to go to properties.  My problem is that there is no box at all.  Same with videos and sites that use the flash player.  There's nothing there to click.  If you were to right click a blank space on any web page and see what it says ie "Inspect Element" "View Page Source."  That's exactly what comes up when I right click where the flash is supposed to be.  Very very frustrating... since I can't find anything online about that specifically.  Everything just says to right click the player that isn't working.  But there's no player there to click.  I can't figure it out.  Any thoughts?
