Flash is basically the only plugin that is really needed for videos,and with the click to play it'll be easy.
Lets not get too paranoid with this move.........it's a good one.
I did not ask for click-to-play or to break the web with this enabled by default. I will say this if moz don't give us a way to fully disable this I will be uninstalling firefox. I do not like any application blocking previous versions of flash and other plugins under some sort of security garbage that you must click to play first.
As the owner of my PC my choice will be to never use firefox if it cant be disabled.
Just like M$ wanting to charge a monthly fee for the windows blue OS and office its my choice to find better alternatives.
I think this is really more a push to html5 but you would have to ask Mozilla that question. I do see your point this will help safe guard users who don't know the web that well and that is a good thing but for the rest of us I want options not forced compliance.
