Filing as a good first bug to learn workflows.
The clang static analyzer (scan-build) found a dead assignment to rv in OpaqueResponseFilter::DetermineContentType. The return value of httpChannel->GetContentType(contentType) is stored in rv, but rv is never read afterwards (the code branches on contentType.IsEmpty() instead). That assignment is dead.
The fix is to call httpChannel->GetContentType(contentType); directly without assigning to rv.
Link to the code:
https://searchfox.org/mozilla-central/source/netwerk/protocol/http/OpaqueResponseUtils.h#175
To verify the fix:
./mach build netwerk/protocol/http
The change should not alter behavior: the result of GetContentType was already ignored; only the dead store is removed.
