Hello, I signed in to Firefox on a new computer and it appears to have synced to the new computer, overwriting and erasing all my bookmarks. I use Firefox at work because I need to move through several computers. Firefox allows me to bring my bookmarks with me to each station. Now it appears I may have erased all my bookmarks by syncing this new computer, not the other way around as it always has. Please help me recover my bookmarks.

Restore Bookmark Backups

Firefox automatically makes backups of the bookmarks. These are stored in the bookmarkbackups folder.

Open the Bookmarks Manager; Press the Alt or F10 key to bring up the toolbar, and select Bookmarks. Hot key is <Control> (Mac=<Command>) <Shift> B. Firefox 84+ <Control> (Mac=<Command>) <Shift> O.

Once the window is open, at the top of the page, press the button labeled Import and Backup. Select Restore. From the list, pick the file you want and click it.

The backups are stored in a jsonlz4 file named something like this; bookmarks-2016-06-29_1424_enD1GTH ya0JmicnYWg4V4g==.jsonlz4

In this example; 2016-06-29 = date created, 1424 = number of entries.

Are you saying the newest member to the sync did not get the bookmarks? or lost the bookmarks it already had?

What about the other members of the sync?


If you have sync, and there is a problem anywhere, Shut Down Sync Immediately On All Devices to prevent the problem from spreading. Type https://accounts.firefox.com/settings<enter> in the address bar. Once the problem is fixed, perform the same repair on all computers/profiles before using sync again.
