Yesterday I logged out of my friend's account on their device without selecting the "delete all data" by my mistake, and logged into my own which syncs all my bookmarks across accounts. After logging in for about 4 hours, I signed out, read long enough to select the "delete all data" checkmark, and shutdown their computer.

This evening, I have realized my account has hundreds of bookmarks unrelated to my account. After some confirmation I now know this information is from the laptop I synced from, and all this data was synced in some 5 hours.

Is there a way I can backup my sync data to the morning before this happened? And if I deleted my friends data, can they recover their bookmarks/browser info another way? (they wouldn't have synced to my data since I deleted only mine after I logged out).

Sincerely, a panicked firefox user.

You can restore a recent compressed jsonlz4 backup in the bookmarkbackups folder to get teh bookmarks back.

The name of an automatically created JSON bookmarks backup in the bookmarkbackups folder includes a total item count (folders and separators included) and an hash value to prevent saving the same backup more than once. You also see this count in the Restore menu drop-down list.

  • bookmarks-YYYY-MM-DD_<item count>_<hash>.jsonlz4.
