For the best user experience with the Posterjack website, you will want to make sure you are using the most up to date version of your chosen web browser. We have found over the years that Firefox and Chrome are the best option, that tend to have the fewest 'gremlins' that pop-up with general web browsing of any kind. Safari, and Edge will also work well with our website. The only browser we advise against using is Internet Explorer. You will run into upload issues with Internet Explorer, as it is a discontinued browser platform. Microsoft has discontinued security and usage updates on Internet Explorer, and the browser will become more and more difficult to use for all internet browsing as time goes on.
