[SOLVED] Firefox and website menus

I have searched a bit on the forum, but must confess that I am not sure what keywords to search so please tell me if this has been covered in another post.
Using Firefox 24 under Mageia 3 KDE on a 64/bit Asus A53S I find that I am not able to get drop-down menus to function, for example, the airport lists and calendar at http://www.usairways.com. These menus function with Firefox 26 running under Linux Mint on my netbook and under Solydx and Solydk running Firefox 25 on the Asus from a Live USB. All configurations have OpenJDK installed and all versions of Firefox have the flash plugin.
I might also add that I also visited a site with access to TV series and was unable to view them in Mageia while all the other OSs work without problem. (Note that normal flash video DO work properly in Mageia.)
What am I missing in the Mageia configuration?
