Cant open Google Calendar in Firefox 3.0.10

[Mega mind]

Hello,

After installing firefox 3.0.10 , firefox can not open my Google Calendar and I made the following response:
"Redirect Loop:

Firefox has detected that the server redirects the request for this address in a way that will not work. The browser has stopped waiting for a response from the site. The site created a redirect so that the request can never succeed.

• Have you disabled or blocked cookies required for this site?
• NOTE: If the problem is not resolved by accepting cookies from this site, it is probably a configuration problem on the server and not your computer. "

Thank you to those who can help me find the solution!

Hey,
Did you by mistake checked the box "when Prevent websites try to redirect or reload the page" in Advanced - General ?
