Description: Instead of offering only hard 1/2/4 hour segments, provide a way to modify the specific range of your history to be obliterated, showing dates and visited sites.

Goals / Use Cases

Goal: add a time selection widget to both provide visual feedback and confirmation of what is going to be removed, and to give the user a finer grained level of control for selecting a specific range.
- Use case: guess that you want to clear about two hours, see that this looks right (or drag the range a little, since it was really more like two hours and 15 min), and then click clear.
Goal: provide more warning before the user clears all of their history
- Use case: user selects "everything" by accident, and they subsequently realize that they don't want to nuke all the history in their profile thanks to the warning interface we have designed.

The largest non-goal is to directly cater to the needs of users who expect the dialog to behave in the same way as the previous version. For instance, if the user regularly opens this dialog to clear all of your active logins, this now a more complex operation since they need to now expand the details are, and also scroll down to get to active log-ins.
Another non-goal is for this dialog to enable a full reset of Firefox (including personal data level things like passwords, bookmarks, new dictionary entries, add-ons and and setting). A total Firefox reset is best handled with some type of higher level profile manager UI, and probably not from inside of the application itself.
