Firefox will time out for a particular page load (for example, if a page doesn't load after 5 minutes of waiting). However, Firefox normally will not end your session on a web site that you are logged in to. Your session on a website may end if: * The site requires frequent activity in order to keep your session going and you are not loading new pages or otherwise making requests to the server * The cookie(s) set by the site expire or get cleared * You are using a site in a private browsing window and you close it Have you noticed a difference between using the site in Firefox and using it in other browsers?
