Personally I think the importance/usage of Firefox is somewhat overstated/over-estimated by this little write up. Sure, it's probably the 2nd most widely used browser around, but its numbers are dropping while Chrome's are rising. Additionally Thunderbird becoming a defacto standard ? What a crock.
Seriously, was this write up written by someone from Hyperion ? It reads more like an attempt to sell something to people than anything else (I dont mean literal currency for exchange for goods/services selling before someone harks up about my choice of words).
The vast majority of people just want something they can browse with and maybe watch online videos/youtube with. Flash is obviously a biggish thing as well for a lot of people, but not really an option for any alternative systems.
edit: good luck to those involved/interested still though.
