I think you're coming at it from a quite different point of view than
browser builders usually have. When we implement e.g. our
localStorage database, having it use the same file format as Opera is
the furthest thing from our mind. Even if we wanted to share data
with them, how would we make sure that we didn't both write the file
at the same time? How would we know when to update our in-memory
state from disk? What if you had multiple Firefox profiles that each
used a different set of cookies--which profile should sync with Opera?
These are huge problems and lots of work, and for very little payoff.
