no, piggybank 2.1 will work on both firefox 1.0 and firefox 1.5

piggybank 2.0 does not have hooks to the firefox extension update
mechanism, also because in firefox 1.0 it's pretty lame.

I'm thinking of adding it to piggyBank 2.1 but it will require you to
run Firefox 1.5 (I think, I haven't done the work yet).

I'm fully aware of the trend to avoid releasing software alltogether and
I share your appreciation for the fact that googlemaps fixes itself,
doesn't have to be you that fix it.

There are parts of piggybank (say scrapers) that will be treated as
'instant update' resources (their freshness is always checked on the web
before being run locally, and ask you if you want to update them before
they get executed) and we'll integrate in firefox's own update mechanism
  and we'll try to make releases early and often.

[note: firefox 1.5 now supports binary diff updates... means that we
they don't have to send you a new browser every time, but only the
binary difference between your version and the new one.... I don't know
if this could be used for extensions as well]
