I thought this might be a Windows issue, but it appears more likely to be a Firefox problem...... Almost every time Firefox updates itself on one of my several PCs (a Dell), all of my saved logins are removed.
After some checking, I found that the actual logins file had been changed from "logins.json" to "logins.json.corrupt".
Why Firefox is doing this is anybodies guess, but it may have something to do with the actual passwords themselves containing characters that it doesn't like.......
Easy resolution - find the "corrupt" file and rename it!
Using Windows Explorer, you will need to make hidden files visible, then go to (User)>Appdata>Roaming>Mozilla>Firefox>Profiles>(71r822oe.*********), then scrol down to "logins.json.corrupt" - select, rename, "logins.json", agree to the change warning, and exit. All now works as before.

Please, Mozilla - can you try and stop this happening in the first place ?
