Backup and Restore
You should know that if you "Clear recent history" in Firefox's web browser cache including:
[ x ] Offline web data
or in Chrome if you "Delete browsing data" including:
[ x ] Cookies and other site data
you will delete your database.
You can back up and move your db to another web browser via the Database Export form. Copy-paste that text to the Database Import form on another web browser. Similarily you can manage your database in multiples when it gets large exporting and importing in pieces. Also similarily you can supply data in the entriesList.js file by entering the "load" command in the search bar.
