This extension creates a backup of the bookmarks at regular time intervals in Downloads directory.
In an unfortunate event, you accidentally delete a bookmark or a bookmark folder, you can simply restore it by uploading the backup file saved in the Downloads directory on Bookmark Manager (Ctrl + Shift + O).
