Yep, I know it's a pain in the ass to rewrite the API 'n stuff to work with Google's Pepper flash plugin, but Flash is practically required to enjoy the Internet. So many DRM'd things, like TV shows, movies, music videos, online games (think faceb00k, not that I use it), etc., etc. use Flash.. and they need the newest Flash for the best experience. By shunning the Google Pepper Flash plugin, Mozilla Firefox is forcing GNU/Linux to be a second-class citizen on the Internet. People can just use Chrome Browser on GNU/Linux instead, but that misses the point.
Pleez Mozilla - Do the Pepper Flash Plugin for Firefox.

Seems like it's a different ballgame this time around because GNU/Linux/OpenGL have the added value of being FASTER than the "other" os:

Wouldn't, "Run your game on GNU/Linux and it will run nearly %20 faster!" seem to be an effective sell to gamers everywhere to you?
Plus, Valve is popular enough that it has the ear (and hands) of the GPU makers to truly make things better for GNU/Linux gaming.
I think they're on to something there... Get your revolution on!
