HistoryBlock is an extension that works almost like to the newly created Chrome's Incognito mode, but without the necessity of switching modes while using the browser (or opening in new windows, etc).
Using this tool you will be able to create a list of hosts to be blocked from the history tab, the recently closed tabs list and the download manager (ctrl+j).
Requirements:
· Firefox: 3.5 – 8.0.*
