I believe Erinn is making a dependency graph and intends on updating
TBB whenever one of the built-in dependencies updates in debian. I
think she even has dreams of a machine doing this for her, and kicking
off automated builds. (I hope she doesn't despise me for revealing the
secrets of her dreams.)

I would prefer it if we can unify our prefs.js use, but I guess you
guys may want to support more things. I think with effort you can even
get flash running safely under a default configuration...

What do you anticipate being the other substantial feature differences
that prevent you from just providing a stock TBB?

Hrmm.. I don't think this will be the case... System extensions seem a
bad idea to source by default.. In fact, we should ensure we do not do
this, due to the potential to source distro branding extensions that
damage anonymity...

Can we figure out a way to come close to a common set of extensions
and configs, so the set of extensions you must add to TBB is minimal?

Do you have a list of your extensions anywhere?

Yeah, it may be some round trips before we figure out new tickets.
