I have used old Kashflow for many years on my Firefox browser. I have recently upgraded to new Kashflow, which worked for 2 days. I now only get a blank screen. Having contacted support the response was, that Kashflow is only supported on Chrome. If you are using a different browser then we cannot provide any support. This is the tail wagging the dog!! Kashflow must be browser agnostic otherwise customer will choose a platform that works for them and not Kashflow
