Then reinstall the latest version.

Note: Windows 8 and Windows 10 have built-in flash players and Adobe will cause a conflict. Install the plugin only. Not the active_x.

On the password issue, let's try this;

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options) key, and then starting Firefox. A small dialog should appear. Click Start In Safe Mode (not Refresh).

After closing Firefox, open it in Safe Mode again. Is the problem still there?

Note: Some software, like Advanced SystemCare with Surfing Protection, can protect files in the Firefox profile folder against changes. If you have such software then check the settings or uninstall this software.

Would have never thought of that and I even ran it in safe mode

well came back this AM and problem was back I may not have tested it correctly as I tried the restore (copy) of the two files right away so I still have the problem of the logins.json file disappearing

Did the issue return when only running in Safe Mode?
