Implemented and packaged version 0.1.4 with the requested recovery-focused changes, while preserving the previous AMO warning fixes.

0.1.4 Release Notes

Session restore reliability fixes

• Reworked tab/session restore so Firefox URL restrictions should no longer prevent tab creation.
• Restore now creates a blank/safe tab first, then navigates it to the saved URL.
• If Firefox rejects a saved URL, the tab remains open as a safe placeholder (about:newtab) instead of failing the whole restore.
• This directly addresses the error:
  Firefox could not create any tabs for this snapshot. Check extension permissions and try again.
• Pinned tabs and active tab selection are still restored best-effort.
• Full restore continues to run in the background script so it is not interrupted when the popup closes.

Restore preview before importing tabs

• Restoring a saved UI snapshot now displays a confirmation prompt listing tabs that will be restored.
• Restoring from an uploaded .ffsession.json / .json file now uses the same preview and confirmation flow.
• The prompt includes:
• total tabs
• pinned tab count
• window count
• first restored tab titles and URLs
• Existing windows remain untouched.

Bookmark point-in-time recovery

Added full bookmark recovery support:

• Snapshot/export all Firefox bookmarks as a portable .ffbookmarks.json file.
• Save bookmark snapshots locally in extension storage.
• Import bookmark snapshot files.
• Restore imported or saved bookmark snapshots.
• Restored bookmarks are placed inside a new restore folder, so existing bookmarks are not deleted or overwritten.
• Added preview lists for bookmark snapshot restore/import flows.

Bookmark search improvements retained

• Bookmark search still shows the folder path where each bookmark was found.
• Search still supports title, URL, hostname, and folder-path matching.

AMO compatibility fixes retained

• Version bumped to 0.1.4.
• Firefox Desktop minimum remains 140.0.
• Firefox for Android minimum remains 142.0.
• data_collection_permissions remains declared as required none.
• Local validation still checks that the AMO minimum-version requirements are satisfied.

Packaging improvements retained

• AMO package excludes .DS_Store, Thumbs.db, desktop.ini, __pycache__, and Python bytecode files.
• New package generated

0.1.2 fixes Mozilla Add-ons manifest compatibility warnings by updating the minimum supported Firefox versions required for the declared data collection permissions metadata. It also includes the 0.1.1 restore reliability improvements, JSON import fixes, safer tab/window restoration, visible bookmark folder paths in search results, and cleaner AMO packaging.

User-facing summary

• Restoring sessions from imported JSON files is now more reliable.
• Restore continues even if the popup closes.
• Unsupported internal browser pages safely reopen as new tabs instead of breaking restore.
• Bookmark search results now show which folder each bookmark was found in.
• The add-on package has been updated for current Firefox / AMO requirements.
