Prepare the backup scope and route; successful restoration and permission to erase the old computer remain unresolved.\n\n## Choose the material and destination\n\nMozilla’s [Export guide](https://support.mozilla.org/en-US/kb/thunderbird-export) describes a ZIP containing the current profile’s accounts, messages, address books and settings. Choose this broader scope deliberately.\n\nThe [profile guide](https://support.mozilla.org/en-US/kb/profiles-where-thunderbird-stores-user-data), profile location and backup sections, explains that profiles also contain passwords and preferences, separately from the application. Use Thunderbird’s troubleshooting information to locate the actual profile; copying the program folder is not this backup. Keep the profile out of public attachments and feedback.\n\n## Choose the size route\n\nThe Export guide supports ZIP backups **up to 2 GB**. For a profile **larger than 2 GB**, it directs manual copying of the whole profile to an empty destination folder. Resolve unknown or ambiguous size before choosing.\n\nThe ZIP route is **Tools → Export**, then export, choose destination/name and save. For a manual profile copy, the profile guide requires closing Thunderbird first. Record which route is intended and which application version/profile it concerns; no copy has been created by this preparation.\n\n## Check the local-mail gap\n\nMozilla’s [IMAP explanation](https://support.mozilla.org/en-US/kb/imap-synchronization), synchronization and storage sections, distinguishes locally downloaded bodies from headers-only messages. A visible message list therefore does not establish a complete local mail copy. Subfolders are not automatically synchronized just because their parent is selected, and age/size settings can limit downloads. The page is dated **October 27, 2015**: use this as a coverage question, not a promise of today’s control layout. Do not change synchronization settings or delete mail as part of this preparation.\n\nHand back the intended profile, route, private destination and unresolved local-content questions. Keep actual contents, readability and restoration as separate checks before any retirement decision. A filename or completion notice is not evidence that the requested records are recoverable.\n\n**Evidence:** Three official Mozilla pages read through **2026-10-05T17:57:07Z**. Export is dated March 11, 2025; Profiles September 13, 2025; IMAP as above. Sixteen synthetic manual decisions checked this preparation; no profile, account, export, copy, synchronization, restoration or erasure was accessed or performed. A distinct same-controller checker reopened all three sources and checked the sixteen author decisions plus eight additional manual boundaries at **2026-10-05T18:04:13.364276Z**; shared control supplies no independent formal coverage. Recheck changed versions, storage scope or guidance before use and by **2026-11-05T17:57:07Z**. Report unclear branches without private profile contents.
