    <p>to make html5rocks demo work on Firefox you need to attach <code>onupgradeneeded</code> event on database open instead of <code>setversion</code> method for creating the database. here is the code sample that works both on Firefox and Chrome:</p> <pre><code>myStorage.indexedDB.open = function() { var v = 1; var request = indexedDB.open("todos", v); //Firefox code for db init request.onupgradeneeded = function (e) { myStorage.indexedDB.db = e.target.result; var db = myStorage.indexedDB.db; // We can only create Object stores in a setVersion transaction; if(db.objectStoreNames.contains("todo")) { var storeReq = db.deleteObjectStore("todo"); } var store = db.createObjectStore("todo", {keyPath: "timeStamp"}); } request.onsuccess = function(e) { myStorage.indexedDB.db = e.target.result; var db = myStorage.indexedDB.db; //Chrome code for db init if (v!= db.version &amp;&amp; db.setVersion) { var setVrequest = db.setVersion(v); // onsuccess is the only place we can create Object Stores setVrequest.onerror = myStorage.indexedDB.onerror; setVrequest.onsuccess = function(e) { if(db.objectStoreNames.contains("todo")) { db.deleteObjectStore("todo"); } var store = db.createObjectStore("todo", {keyPath: "timeStamp"}); myStorage.indexedDB.getAllTodoItems(); }; } else myStorage.indexedDB.getAllTodoItems(); }; request.onerror = myStorage.indexedDB.onerror; } </code></pre> <p>Edit: Here is a link to working version of the html5roks ToDo demo, which I maintain on <a href="https://github.com/denimf/IndexedDbToDo" rel="nofollow">github</a>, expanded with two new features for viewing details data and updating values.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
