Description

[Eli Grey (:sephr)]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1
Build Identifier: 

In Options -> Advanced -> Network, there is box that says, "The following websites have stored data for offline use:"
This box never actually shows sites storing data for offline use.

Reproducible: Always

Steps to Reproduce:
Reproducing via JS Shell
1. Type globalStorage['example.com'].example = ['Some','example','array']l
2. Check offline data management box

Or via website in bug report
1. Type some text (will be stored in globalStorage)
2. Check offline data management box
Actual Results:  
Box is empty and a normal user would never know storage space (up to 500MB or whatever browser.cache.offline.capacity is set to if not default) is being wasted on their computer's storage space.

Expected Results:  
For JS Shell method: expecting to see that example.com is storing offline data on my computer and I have the option to remove it.

For website method: same as previous but with noteboard.eligrey.com
