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.

Unfortunately these were last updated in 2018 and do not include the ones saved up to and including last week. Thank you for the help as it will help next time I update.

Bookmark Backups Settings

Firefox automatically makes backups of the bookmarks. These are stored in the bookmarkbackups folder. You can set how many backups are kept by doing this;

Type about:config<enter> in the address box. If a warning screen comes up, press the I Accept the Risk button. At the top of the screen is a search bar. Type browser.bookmarks.max_backups

The values for this setting are; -1 = unlimited number of backups 0 = Do not create any backups Any other number here will keep that many backups Example: 5 = 5 backups are kept.

The backups are stored in a jsonlz4 file named something like this; bookmarks-2016-06-29_1424_enD1GTHya0JmicnYWg4V4g ==.jsonlz4 In this example; 2016-06-29 = date created, 1424 = number of entries.
