Hello Firefox Support, I’m reaching out for assistance regarding a serious data loss issue I experienced. Recently, I accidentally launched an older version of Firefox on macOS using my existing profile. After this, I noticed that all my Multi-Account Containers were still listed, but all cookies associated with those containers were completely lost. I understand this might be caused by incompatibility between Firefox versions and profile structures. I have located files such as: - `cookies.sqlite` - `containers.json` - `sessionstore-backups/upgrade.jsonlz4-*` However, none of the cookies appear to have `originAttributes` associated with containers anymore (only empty strings). Is there any way to recover or reassign the lost cookies to their original containers? This incident has affected multiple work logins and multi-account configurations I heavily depend on. Thank you for any support or tools you can provide to assist in restoring the lost data. Best regards, Thang
