Comment (by mcs):

 An update to the same version should work. But then you would need to
 always build with the same version (so you could use a pre-signed MAR file
 that has that version embedded in it).

 I think Mozilla avoids these problems by creating nightly or test builds
 with different signing certs in them and also a different value for
 ACCEPTED_MAR_CHANNEL_IDS inside browser/confvars.sh. If we only need to
 test with nightly builds that we do not expect regular users to ever use,
 we could adopt that kind of approach. Then both incremental and full
 updates could be tested because the tests could generate signed MAR files.
