@Proton2: Well, given the error message, the problem has to do more with their browser detection strategy than it does their scientists or some anarchistic philo$ophy.
Send the site admins a note informing them that the way in which they are determining browser version is too limiting. Best to test for modern browser capabilities, not parse user agent strings. Further, tests for browser version are better served with the greater than approach versus the equality one.
This is what the spirits tell me.
