Examine Offline Data (Cookies, HTML5 Storage)

Inspect cookies and HTML5 web storage data (localStorage and sessionStorage) stored by a web page.

You can easily check if a website stores your credit card information in a cookie! The tool can also aid in debugging web pages that store offline data.

If your actions on the web page cause changes to the stored data, you can invoke the extension again, to view the updated data. You can also remove cookies or web storage data by clicking the “X” icon that shows up on hovering on individual items (or section headings).

A future version of the tool will automatically watch cookies and web storage data for changes as well as allow you to edit them inline.
