I am a hipster Flash hater. I hated Flash before Steve Jobs told it was bad. I hate Flash before Adobe said there would be no Flash 7 for Linux. I don't have Flash on my machine. I even coined "fc;dw".
I have been muling over an idea for far too long, and an enlightning conversation with fellow Mozillians made me do it Tuesday night.
I therefor introduce a proof of concept Firefox add-on: No Flash.
