Mozilla at one point had momentum before Chrome came up and wasted it while letting Firefox become slow and memory hog (This was before Chrome came out, I am not commenting on latest versions). I don't see Mozilla turning around because they are trying to be followers where both Apple and Google are executing well enough at least to maintain Status quo. Why go after Smart Phone Market while at best you can be 3rd or 4th best (with less than 5% market share)?
