Linux Academy

Hello. I'm new to this forum and FreeBSD. I was wondering if anyone else is having trouble viewing Linux Academy videos on Firefox/Chromium? I followed the handbook instructions for installing flash, and it works on other sites except this one. Does it just not work on FreeBSD?
Flash works fine on Firefox but Chrome/Chromium no longer uses the plugin for Flash (cause Flash is dead and Google took it out).

Did you quit out of Firefox after installing everything? Did you run the nspluginwrapper -a -v -i for each user?
