Hi, I have firefox (latest version) working on windows 10 enterprise. Now I have to move to a Mac (MacOS Mojave 10.14.3), I installed the latest version of firefox and then copied my profile folder (from the roaming app data) to the corresponding location on MacOS.

Everything works fine except that if I try to login to websites it auto-fills the username field but not the password field. If I open about:preferences and go to the security-saved logins it's completely empty.

I tried to copy again key3.db key4.db and logins.json but nothing.... Also if I login to a website I'm prompted to save username and password, I choose save but it is not saved....

Bookmarks and history instead are ok.

P.S.: I don't use Firefox sync and I can't use it I have some sensitive logins stored on Firefox.

Many thanks in advance to anybody that can help me.

Hi FredMcD, I already tried, look at my post:
