Choosing a different partner seems like the most mission-aligned option for Mozilla.
Choosing a different partner seems like the most mission-aligned option for Mozilla.
FF, for instance, made their multi-browser "sync" horribly complicated for users, to preserve zero knowledge, which is the opposite of what 99% of users wanted.
Chrome made it simple (and THEN added a fairly decent ZK option buried in advanced).
What makes Mozilla/Firefox relevant is having enough users that it can't be ignored. Mozilla is already increasingly irrelevant due to mobile (Firefox OS is nice promise, but Safari and Chrome are dominating the space); marginalizing their desktop product doesn't help.
Now, if the question is whether adopting Yahoo & co will be bad for the user experience, Mozilla is betting on the fact that these smaller search providers can deliver not just a comparable experience, but also innovation from many sources.
