After computer refresh most bookmarks were missing because the refresh uninstalled Firefox. I was able to restore most of them from a backup created and saved by Firefox. Problem is it was 3 months old so that Bookmarks created in the last 3 months were not restored.

How can I set up an automatic bookmark backup to create a new backup every 30 days?

Also, when Firefox is uninstalled and then reinstalled on the same computer is the program able to restore all prior settings from the profile folder?

Thanks !

1. Firefox doesn't have a feature for doing a bookmarks backup on anything but the automatic once a day backup that has been a part of Firefox for many years now. The current version of Firefox saves 15 backups, one for each of the last 15 days that Firefox was used.

2. Uninstalling Firefox doesn't remove the Firefox user data which is stored in the Profile folder. So when Firefox is re-installed it will find the Profile and use it.

Firefox creates a JSON backup in the bookmarkbackups folder. A new backup is only created when there is a different hash value calculated.

You would have to backup the content of this folder manually to be sure to keep the backup in case of profile issues or when a new profile is created.


You can make Firefox create an automatic HTML backup (bookmarks.html) when you exit Firefox if you set the browser.bookmarks.autoExportHTML pref to true on the about:config page.

This backup is created by default in the profile folder as bookmarks.html every time you close Firefox, but you can set the path and file name via the browser.bookmarks.file pref on the about:config page.

The browser.bookmarks.file pref doesn't exist by default and you need to create a new String pref with the name browser.bookmarks.file and set the value to the full path of the backup bookmarks file including the file name.

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
