I'm also happy to put you in touch with Luis Villa, who was
responsible for much of the MPLv2 process
There are only two cases i'm aware of in which MPLv2 is GPL incompatible.
1. The author of the code has attached a notice stating the code is
"incompatible with secondary licenses", under section 1.5 (using the
notice in Exhibit B, as per section 10.4)
2. The original code is MPL 1.1, you use section 6.2 of the MPL 1.1 to
use the code under the terms of "any subsequent version of this
license", and the original code was not dual licensed to make it GPL
compatible. This is also covered by section 1.5.
So without doing anything, unless you fall into situation 2, or have
code that falls into situation 1, MPLv2 is a GPL compatible license,
because it allow distribution under the terms of a Secondary license
(defined in section 1.12), per section 3.3
