This extension utilizes the "Clear Recent History..." feature that is part of Firefox version 1.5 and above. It makes this feature a lot more accessible via right-click context menu and an optional toolbar button.
IMPORTANT: As many of your favorite extensions, THIS ADD-ON DOES NOT WORK WITH FIREFOX 57 and later! Unfortunately, there is no way to implement this feature in FF 57++ using the new WebExtensions-format. I'm sorry, but it's up to Mozilla...
