New description:

 Reduce fingerprintability and solve Windows reproducible builds problem by
 replacing the current Chome-based C++ WebRTC implementation with Firefox's
 built-in WebRTC implementation.

 Update: After discussions with dcf, it looks like fingerprintability is
 not much of a concern and in any case would be no different with Firefox
 vs Chrome. Also, since meek is moving to uTLS instead of Firefox this
 isn't necessarily more convenient.

 Leaving this ticket open just as another alternative for looking at
 different WebRTC implementations (related: #28942)

Comment (by cohosh):

 Firefox is likely not the answer here as the workflow and details are very
 close to Chrome. Fingerprintability is not at the moment a problem, nor
 would Firefox likely provide a solution better than the current Chrome
 library.
