When I go to a site, Firefox doesn't fill in the username or password. I must look them up in my keychain and enter them manually. It's a BIG PITA. and this is only since said update. I've tried all the recommended fixes, but no good.

Is this a problem with the Keychain Services Integration extension or also with the Firefox Password Manager?

Is this setting still enabled?

  • Firefox > Preferences > Security: Passwords: "Remember passwords for sites"

It is possible that there is a problem with the key3.db and signons.sqlite files that store the encrypted names and passwords in Firefox.
Rename the key3.db and signons.sqlite files in the Firefox profile folder.
You can add .old to the file names (key3.db.old and signons.sqlite.old) or move them to another folder to make it possible to undo the action.
You need to set a new Master Password after renaming or deleting key3.db and all currently saved passwords are lost.
If that has worked then you can remove the renamed files that are no longer needed.
Otherwise you can rename the files to their previous names (signons.sqlite and key3.db).

You can also check for issues caused by an extension that isn't working properly.
