User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:14.0) Gecko/20120514 Firefox/14.0a2 Build ID: 20120514053159 Steps to reproduce: I opened a new tab and the new tab page appeared. Actual results: The tab page is showing me screenshots of my favorite websites. In particular, it's displaying a screenshot of my bank website with the 3 first numbers of my client ID I'm typing every time I want to access my accounts in a text input. Expected results: User inserted content shouldn't be displayed in these screenshots, or maybe at least for secured website?
