Issues backing up / restoring Brave Browser Profile on Linux

Greetings,

I am back with the findings on what passwords end up going missing. I see three ways passwords come up missing migrating from Mozilla Firefox to Brave Browser:

  1. Mozilla used to support browser based FTP connections. I had some such passwords yet in my password file. Years ago I had moved all of my FTP connections to a separate Mozilla Firefox profile dedicated to running the FireFTP extension. No issue here.

  2. I had forgotten that Mozilla browsers sometimes captured multiple passwords for the same site. Indeed, I had duplicate entries at times. Brave de-duped the passwords. No issue here.

  3. And here is where it gets interesting… there are a handful of passwords that Brave Browser flat out skipped migrating. I am guessing that is what happened to “one of my two always open” websites the first time I attempted the migration. There are no unique characters in the passwords, not an unusually short or long password (typical is between a length of 8 to 16). I think this is the only area that deserves continued looking into. How may I assist in this investigation seeking a solution?

I am thankful,
Michael
