This morning Firefox upgraded to 3.6.15 and a long running application now no longer works. The application (written in PHP) tries to retrieve a cookie when the login is processed. If it can not find the cookie if presents a page to get location/extension information, then saves that in a cookie and returns to the login page. Starting this morning (with the update) the application acts as if there is no cookie present, and goes into an endless loop, asking for the location/extension infomation. Before I tear the code apart I thought I would check to see if this is a known problem and/or solicit suggestions.

WinXP SP3 and Ubuntu Linux 10.4 LTS act the same bill
