Because about:blank has been deprecated and is no longer the default option for a blank page. This is the only supported ways to retain the behavior you want. That is to say about:blank will always be valid uri and provide an empty sheet of paper.. but using it in the manor you want is not supported beyond what has already been stated.delicacy wrote:well, from firefox up to palemoon, i never had issues using the prompt for session to load, & i would still get new pages as "about:blank" normally sets them.
anyways, it's now resolved.
thanks
