I'm on macOS Sequoia 15.6.1 and using Thunderbird 142.0 Everytime I open Thunderbird, it keeps asking me to enter passwords for my accounts (IMAP and CalDav), even though I checked the checkbox to store them. In Thunderbird settings, I can see that the passwords are stored. What I have tried so far: - Even though I would prefer using Thunderbird to store passwords, I checked the box for "Require device authentication to fill and manage passwords" (translated into English by myself, not sure if that's exactly the English version) but after restarting Thunderbird, that checkbox was not checked anymore - Delete logins.json, key4.db and cert9.db as well as pkcs11.txt to have them recreated (they are and they contain encrypted passwords) - In about:config, set signon.management.page.os-auth.enabled = false signon.rememberSignons = true ldap_2.servers.osx.dirType to -1 ldap_2.servers.osx.uri to empty - Give Thunderbird full disk access in macOS settings because I thought it might be a permission issue (even though my Profile folder is marked as read&write and even though the passwords seem to be written in the files as described above) - Start from terminal with option -passwordstore=basic with the following logs: CoreData: error: Unhandled error occurred during faulting: Error Domain=NSCocoaErrorDomain Code=134092 "(null)" ({ }) 2025-09-10 14:17:47.166 thunderbird[10926:228127] Rethrowing (from nts_ValueForProperty:) NSInternalInconsistencyException: Unhandled error (NSCocoaErrorDomain, 134092) occurred during faulting and was thrown: Error Domain=NSCocoaErrorDomain Code=134092 "(null)" CoreData: error: Unhandled error occurred during faulting: Error Domain=NSCocoaErrorDomain Code=134092 "(null)" ({ }) 2025-09-10 14:17:47.414 thunderbird[10926:228127] Rethrowing (from nts_ValueForProperty:) NSInternalInconsistencyException: Unhandled error (NSCocoaErrorDomain, 134092) occurred during faulting and was thrown: Error Domain=NSCocoaErrorDomain Code=134092 "(null)" CoreData: error: Unhandled error occurred during faulting: Error Domain=NSCocoaErrorDomain Code=134092 "(null)" ({ }) This log is repeated multiple times - Based on that, I deactivated access to Contacts in macOS system settings for Thunderbird
