For days I had been trying to figure out why the build in PW manager in FF on Android stopped working. After reaching out and not getting any answers here I finally found the answer. Here: https://www.reddit.com/r/oneplus/comments/gbdab7/lockbox_not_opening/ You phone security and lock screen is preventing FF mobile from opening the build it password manager. It DID work on previous versions of FF because I have always had my lock screen on Note 8 set to drawing a pattern to unlock phone. But in latest version YOU broke it Mozilla!! The build in version does not require downloading the FF lockwise addon either! It's very easy to re-create the issue. Turn any of your phones security lock screen logons to anything but NONE and it will break the function of FF Lockwise! Thanks goes to the person who created the reddit post!
