HTML5 Guidelines for Web Developers

8.1 Storage 211

Figure 8.2 The Firefox add-on Firebug displaying “sessionStorage”

You can download the Firefox add-ons from these Internet addresses:

z Firebug: http://getfirebug.com

z sqlite-manager: http://code.google.com/p/sqlite-manager

Apple’s Safari offers an integrated debugging option, which first needs to be en-
abled in the Advanced Preferences. After activation, Safari shows a new Develop
menu with a console that can display the storage content, just like Firebug.

Google Chrome and Opera also have integrated developer tools, allowing for very
convenient access to all website elements. In both browsers, the Storage menu
offers a clear and detailed list of localStorage, sessionStorage, and Cookies. In the
table you can also add values, change them, or delete them (see Figure 8.3).
