The places.sqlite file in your profile folder stores your bookmarks and history. You can replace this file with a backup copy while Firefox is closed.

• Profiles - Where Firefox stores your bookmarks, passwords and other user data

You can also import bookmarks from a backup in HTML format. The key difference is that this will add those bookmarks to the existing ones, rather than replacing the whole set with the backup.

• Import Bookmarks from an HTML file

Note that replacing places.sqlite restore the bookmarks and the history as stored in the file. Restoring a JSON backup replaces all bookmarks with the bookmarks in the file.

I'm not sure if I understand how or when you want to restore bookmarks.

Are you doing this that often that you want to do this in a different way?

thnx Gingerbread Man and COR-EL for your reply.

cor-el, basically i am working on a small project by which we can restore bookmarks in mozilla. i am able to get backup file(json) but i need an option by which user only select path of that backup json file and it should automatically restore that file in mozilla. i dont want to write sql query for that. if you have any other idea please suggest. thnx :)

A way to restore bookmarks automatically is to delete the places.sqlite and place the JSON backup as only or most recent bookmarks.json file in the bookmarkbackups folder.

thnx COR-EL, its working. :)

One more thing is there any way to merge two .json files. say i want my old bookmarks to be there if i restore with new backup file.

thnx again for the solution :)

You can only merge bookmarks by importing an HTML backup because restoring a JSON backup will replace all existing bookmarks.

ok. thnx for your help :)
