Description

Last year
I wrote new separate DOH implementation this weekend and then I noticed that in many DNS response packets with CNAME present there's also a type A or AAAA included.

I think Firefox should prefer the bundled A/AAAA data to the the CNAME to save itself from doing more requests that will take more time. The current code will always "chase" the CNAME if such an entry was present.
