Do you mean names and passwords in the Password Manager or do you mean that you are no longer logged on to (remembered by) websites after closing and restarting Firefox? There is a difference between remembering the name and password in the Password Manager and a "remember me" check box on a web page to log you in automatically. The latter usually involves the creation of a special "remember me" cookie that is stored on your computer and that is send to the server. If this "remember me" cookie is removed or gets corrupted or is not send to the server then the server won't remember you and you will have to sign in once again. You can remove this "remember me" cookie to make the website forget you and require you to sign in again. Clear the cache and remove cookies only from websites that cause problems. "Clear the Cache": *Firefox > Preferences > Advanced > Network > Cached Web Content: "Clear Now" "Remove Cookies" from sites causing problems: *Firefox > Preferences > Privacy > "Use custom settings for history" > Cookies: "Show Cookies" You can inspect and manage permissions for the domain in the currently selected tab via these steps: *Click the "[[Site Identity Button|Site Identity Button]]" (globe/padlock) on the location/address bar *Click "More Information" to open "Tools > Page Info" with the Security tab selected *Go to the Permissions tab (Tools > Page Info > Permissions) to check the permissions for the domain in the currently selected tab
