Didn't have to enter my Master Password when using Firefox on my iPhone
I have a master password set on Firefox on my PC but when I synced my account to my iPhone I was able to login to web sites requiring a password without having to enter my master password on the iPhone.

Thank you for giving Firefox for iOS a try!
Master passwords are local to the device. Master passwords do not affect Sync and master passwords are not required to retrieve your stored bookmarks on Sync.
