Steps to reproduce:

In Firefox13,I just opened a series of html pages and then I exited firefox after finishing work.


Actual results:

When I again opened firefox, and clicked the new tab , it showed me the thumbnail snapshots of the sites which I had visited earlier.At this point,the New Tab page did indeed clearly reveal the content of my earlier secure browsing.Even if you turn off the thumbnail display ,the contents of your HTTPS pages may very well end up in the Firefox cache anyway.Even the cache keeps a detailed record of your browsing history and hence its insecure.


Expected results:

The thumbnail snapshot details of earlier browsing should not have been displayed in new tab .So, its insecure
