User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:8.0) Gecko/20100101 Firefox/8.0
Build ID: 20111104165243

Steps to reproduce:

Data placed in LocalStorage using JavaScript interface cannot be accessed or deleted by the user through the user interface. 

Actual results:

I clicked "View page info" and clicked the tab "Security". In the section "Privacy and security" LocalStorage is not listed. Because this functionality is is similar to cookies I would expect this to be listed in the same section. However this is not the case.

In fact the following is displayed:

"Is this web site storing information (cookies) on my computer? No"

This information is incorrect, in this case I have filled up the LocalStorage up to its full capacity yet Firefox says there is no information stored on the computer.

Expected results:

I propose that Firefox should display the following information:

- There is information stored from this host on this computer.
- The key names and values of this information should be displayed somehow.
- The allocated space for this host should be listed, and preferably a setting to change the amount of space allowed for LocalStorage per host.
- The amount of space used by this host.
