Great extension, but missing the one thing I need Rated 4 out of 5 stars

This does what it says on the tin, the UI is easy to use, and the extension is very helpful. I also appreciate the calendar format of the time range. It is indeed very specific, down to the minute and second.

This extension would be better if:

1. "Browsing & Download History" were separated into 2 categories, the way they are on the "Settings" button in Firefox's "Privacy" tab.

2. The extension maintained the time range after closing, instead of having to be reset upon each new session.

Why I uninstalled Precise Clear History:
I like to keep my Download History far longer than my Browsing History. Unfortunately, this add-on doesn't have separate options for the 2, so I'd lose my download history when I removed the browsing history.

Note: This extension does have a "Session History" option, but of course, it doesn't deal with Browsing History.

This review is for a previous version of the add-on (1.2.1-signed.1-signed). 

This extension doesn't change any built-in capabilities.
What this extension does is add the date range to already existing "Last hour", "Two hours", "Four hours", "Today" and "Everything" selections. It doesn't change or add anything else.

As of time range being restored, well, personally I would be annoyed if it would reset itself each time I open that window...might add an option for that though.
