Tim, please help to investigate this bug, thanks.

We had tested this with disabling the network predictor. The result shows that no cookie of empty firstPartyDomain been set for certain websites, which means disabling network predictor fixes this issue. But Cynthia will run a full test of top 100 websites to verify this.

Some firstPartyDomains are still empty after disabling "network.predictor.enable-prefetch" and "network.predictor.enabled". 

Test report:

After Bug 1305592 is resolved, I will verify this issue again. Thanks.
Depends on: 1305592
Priority: P1 → P2
Once bug 1312954 was resolved, this bug should be fixed even if network.predictor preferences are not turned off.
