MAF's tendency to corrupt backups is unacceptable, and UnMHT is always perfectly reliable. UnMHT has proper error handling, alerting the user when something can't be saved, while MAF pretends nothing went wrong and destroys your data.

As long as Firefox has non-e10s mode, I will stick with UnMHT. The loss of performance is a pain, but it's worth it to avoid MAF.
