The only browser that the system supports is IE , Mozilla Firefox and Google Chrome. We recommend the most (sic) IE browser.
Excuse me while I check the calendar. Yup, it does say it is December, 2016. And yes, that is a message I received from a web site that I was having trouble entering data on. Data that is mission critical. Data, that is consumed by a python application on the back end where the servers that are serving the data are Linux based and the processing is done in an AWS environment. And yet, the code the browser is using is specifically written to run best on Microsoft Internet Explorer. And I wish I could say this is an anomoly. I am still encountering websites that require Flash, or versions of IE that are so old that their security risks have security risks. And yet that is the state of the art in a day when most people are making transations via the mobile devices, which are either on i-devices (which primarily run Safari) or Android devices, that primarily run Chrome. Sure you can load Chrome on to i-devices, or other browsers, but 99% of users do not, and for a good reason. Why would you?
I abandoned Windows completely about a year ago for Mac. Yes, I still have one laying around somewhere, but I have not turned it on in several months, and it would take hours to come up to speed with the 10,000 patches that probably need to be applied. But even I do not use my Mac that much anymore. For example this post is being written on my iPad. Yesterday I was doing a number of things in my AWS envrionment from this same iPad. And if I had a monitor handy, I could do it from my iPhone. Why do I need to carry a laptop anymore? Why do I need to have a specific operating system any more. I do not need a specific a browser to create this post, so why do I need a specific browser to type in data to a form on a web site! This is not 1999. If you are still restricting your broswers, it is time to upgrade your application development. Or you will lose customers. Or at least annoy them to the point that they will not be giving you good reviews on-line.
