I lost all the bookmarks suddenly where i was using this browser for office work, there was no action taken from my end like deletion or any upgrade, however suddenly when i start machine today, i found all bookmarks lost. To restore backup I entered to Profile --> bookmark backup this file is extension JSONLZ4 which is not visible during restore bookmark.

This is quite important to recover these suddenly lost all bookmarks, so is there any way or support available?

Unfortunately this is first time i am facing such kind of issue, So kindly also let me know if we should trust mozilla firefox as default browser and to save bookmarks?

Thanks & Regards

What about the rest of your profile? Settings, bookmarks, history, passwords . . . .

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.
