User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:29.0) Gecko/20100101 Firefox/29.0 (Beta/Release) Build ID: 20140117030207 Steps to reproduce: I'm running Windows 7. I have the task bar always visible. I recently clicked the history button in the new menu and it showed the history entries. The entries went all the way down to the bottom of the screen and below the task bar. The "show all history" entry was not clickable as it was at the very bottom. I first thought that the entry had been removed but when I made the task bar auto hide, I was able to find it. I'm attaching a screenshot of it in action.
