How to restore bookmarks from a bookmarksbackup .jsonlz4 file on a mac

Hello, FF 139.0.4 on MAC Sequoia15.5. Lost ALL references to bookmarks, i.e. Bookmarks Toolbar totally gone. How can/do I restore from .jsonlz4 file in bookmarkbackups. Also, will I be able to salvage my previous profile, presumably containing my older "Tabs on Bottom" work-around? Alternatively, is there a process to restore JUST Firefox from Time Machine? Appreciate any advice.

Just tried this AI response: 'To restore bookmarks from a bookmarksbackup.jsonlz4 file on a Mac, you need to use the Firefox browser's "Restore" feature within the Bookmarks Manager. First, locate the backup file in the bookmarkbackups folder within your Firefox profile. Then, in Firefox, open the Library window (Bookmarks -> Manage Bookmarks or Ctrl+Shift+O), click "Import and Backup," and select "Restore." Choose the jsonlz4 file and confirm the restore operation to recover your bookmarks. " Worked temporarily - i.e. bookmarks toolbar displayed faintly, then the moment I tried to switch to them they disappeared.
