''locking as a duplicate - https://support.mozilla.com/en-US/questions/894853'' My website's ip address changed, and since then mozilla shows an error page ("You see this page because there is no Web site at this address") unless you clear the cache history. I see that the default option in mozilla firefox is not to clean the cache history. Does this mean that all my clients who have visited my webpage via firefox before i changed ip address will not be able to view my webpages? Or will the problem resolve after some time? Is there anyway to solve this problem?
