I have been out of FC development the past few months, but getting back into the game.
I develop mostly with Firefox because I'm more used to Firebug than Safari's (or Chrome's) developer tools.
In the FC config I have setup a 1.1 dev store that links to an online host, but I develop mostly locally. This doesn't cause problems in Safari or Chrome, the cart session is preserved between pages. But in Firefox its not kept locally (so the cart is empty for each page visit).
I thought I knew why that was etc. but perhaps I forgot. Any tips how to get it to work in Firefox?
