This add-on will automatically delete your entire browsing history whenever you navigate to a new page, keeping your history nice and clean.
Setting Firefox to "never remember history" will just force it to always use Private Mode. However, many of us don't only use Private Mode when they don't want their surfing history to be saved, but also, for example, when they want to surf the Internet with a different set of add-ons enabled, but still don't want their surfing history to be stored in "regular mode". This add-on will allow you to do just that.
Explanation of required permissions:
"Access browsing history" – Allows the add-on to delete your browsing history
"Access browser activity during navigation" – Allows the add-on to run every time you navigate to a new page
