This can be done with a copyleft license, as long as you don't want to
take other people's copyleft code (i.e. contributions to your project)
and sell it along with yours. If you do want to do that, then we have
the asymmetric situation people complain about - you get to sell their
copylefted code, but they don't get to sell yours.

This can also be done with a copylefted license - you always get to use
improvements to your own code.

Except that the Mozilla codebase has effectively no "original author"
who can do that any more - the copyright is owned by thousands of
different individuals.
