I was missing this so much! Rated 5 out of 5 stars

As web developer I really need this option, to clear cache and cookies when I restart my browser.Whether there is need to clear my data always depends on my current work and it's impossible to make a fixed decision matching every shutdown. I will never understand why the Firefox crew removed it, whatsever, now the pain is gone.
Wonder why I did not find it earlier.

This review is for a previous version of the add-on (1.0).
