Transferring saved logins from old to new
I'm trying to transfer the saved logins from version 52 ESR to the current version, 86. Nothing has worked so far. I deleted the logins.jason, key3 and key4 files from the version 86 profile folder and then put the logins.jason and key3 files from version 52 in there, with no success. Any working methods?

Thanks for the reply. The only issue with this method is that i am giving all my logins to mozilla. Not a very comfortable idea.
The sync data on the servers is encrypted by your e-mail and a password you choose.
Firefox 52 uses key3.db for the key file. In Firefox 73 support for key3.db has been removed, so you will have to install an intermediate version like Firefox 68 and use this version with its own profile to migrate logins.json and key3.db from 52 to logins.json and key4.db that can be used (i.e. copy these files to the 86/87 profile. in a release profile. You can also consider to install Firefox 52 and update this version until you reach the current release to ensure proper migration of all files.

Use the profile manager to create a new profile although Firefox 68 might do this by default.
