I'm testing access to an app on an internal web server and am noticing that Firefox is not asking to store AGOL credentials after I've supplied them via the Identity Manager. However, Chrome stores the username and password without a problem.
I've tested this with both 1.3 and 2.0 developer editions.
Is there a basic config that I'm overlooking that would account for this disparity? In Firefox I have my web app's URL listed as a trusted sites/always allow cookies, etc.
