Mozilla is the only hope left in the browser market. The rest are controlled by mega corps. Witness the recent ramrodding of video DRM into W3C standards by Google, Microsoft and Apple, all of which have their own DRM implementations.
Not to mention Firefox being forced to support H.264 playback, after Google promised and backtracked on removing support from Chrome. Based on the above two cases, I guess it's already too late, corporate control has taken over the web.
