If you choose to sync your browser history through firefox sync, does mozilla have a way to generate the relevant cryptographic keys to decipher your data on their servers? I know that they say even Mozilla doesn't have access to your data - even when at rest - but I also noticed that they don't seem to utilize the term "zero-knowledge encryption." In other words, does mozilla have the technical capacity to decrypt data synced via mozilla sync?

No, data is encrypted locally with a key derived from the password of the Sync account that only you know. Only this key or a recovery key you can optionally generate can decrypt the data stored on the Sync server.
