You should define the path on which the cookie exists to ensure that you are deleting the correct cookie   function set cookie name  value      document cookie   name       value     Path        function delete cookie name      document cookie   name      Path    Expires Thu  01 Jan 1970 00 00 01 GMT        If you don t specify the path  the browser will set a cookie relative to the page you are currently on  so if you delete the cookie while on a different page  the other cookie continues its existence   Edit based on  Evan Morrison s comment  Be aware that in some cases to identify the correct cookie  the Domain parameter is required  Usually it s defined as Domain  yourdomain com  Placing a dot in front of your domain name means that this cookie may exist on any sub-domain  www also counts as sub-domain      Also  as mentioned in  RobertT s answer  HttpOnly cookies cannot be deleted with JavaScript on the client side

I m not really sure if that was the situation with Roundcube version from May  12  but for current one the answer is that you can t delete roundcube sessauth cookie from JavaScript  as it is marked as HttpOnly  And this means it s not accessible from JS client side code and can be removed only by server side script or by direct user action  via some browser mechanics like integrated debugger or some plugin
