Can anyone talk me out of the Firefox password manager? It has a poor "general" use case for non-website passwords and treats mobile as a second-class satellite, but it seems to just work and the sync between mobile and desktop is very handy.

I read and understood just enough of this when it was published to know it would make the foundation an object of ridicule if it was ill-conceived, but I obviously rely on implementation details being tickety boo.
