I just googled a few URLs here, and found the following:
mozgcp.net is the Mozilla Google Cloud Platform, looking at the links it connects to, it looks as if it is accessing settings for Google, then finding some certificates, accessing pictures for the Pocket service and doing some product detection, why, I have no idea.
moz.works is Mozilla's content delivery network, porbably nothing to worry about.
