I think it must be a typo. 
In file netwerk/streamconv/converters/nsHTTPCompressConv.cpp:

            case GZIP_EXTRA1:
                iStr->Read(&c, 1, &rv);
                streamLen--;
-               mLen = ((uInt) c & 0377) << 8;
+               mLen |= ((uInt) c & 0377) << 8;
                mSkipCount = 0;
                hMode = GZIP_EXTRA2;
                break;

mLen should be calculated from 2 bytes XLEN according to rfc1952:

      (if FLG.FEXTRA set)

         +---+---+=================================+
         | XLEN  |...XLEN bytes of "extra field"...| (more-->)
         +---+---+=================================+
