Users not staying logged in using Firefox

[BryanG]

I'm running both Photopost and Reviewpost on my site, both are integrated with IPB.

Ever since I updated PP and RP to the latest version, I have been getting complaints from users that they aren't staying logged in in Firefox, but they have no problems whatsoever in IE.

I haven't changed my cookie settings and quadruple checked that all of them have the same settings, yet users are still getting logged out.

I've also started experiencing this problem as well.

Any suggestions?
