Mozilla and PHP Sessions (developer must-read)

I have found a problem with Mozilla and cookies (in turn, PHP sessions).

I have tested both in Mozilla and IE.

When I connect to a page, say, [url]www.internationalscholarships.com/cobrand/[/url], and I click a few links, it starts to “lag out”. You won’t be able to load another page in the entire site until you clear your cookies. I have struggled to find the problem in my code that caused this. The problem went away when I removed session_start() from the header file.

Great news, now I have a hint as to what’s causing this. So, for some reason I started to become suspicious of the way Mozilla Firefox handles cookies. I loaded up IE and connected to [url]www.internationalscholarships.com/cobrand/[/url]. I could click around flawlessly, the page never took more than a split second to load. I went back to Firefox and tried again, and it lagged up again.

While I want to say that it’s Firefox that’s causing this problem, I don’t see it happen on any sites other than my own (as far as I know). Has anyone had any experience with such a problem? Anyone have any related info?
