Web browsers are not all the same. Internet Explorer for example does Microsoft specific technology like Active X, and Microsoft’s newest browser Edge doesn’t do Active X. Why is this important? This is just one technology that differentiates what browsers can do.
I had a client who was frustrated she couldn’t get to her website because of the unique way that the developer set it up. The developer set up a non-standard challenge dialog box that you had to answer correctly before you were able to log into the normal login admin area. The problem with this was that Chrome didn’t recognize this probably because it was depending on ActiveX technologies, and Internet Explorer did recognize it.
Often clients complain that they used to be able to have some functionality of a website that worked with their favorite browser, but it stops working. In almost 99% of the cases, that website has stopped supporting their old browser. People tend to take the easy route and that is using IE. Often because people don’t run software update, it means that their version of IE is years out of date. Most of the time installing Chrome or Firefox and importing their bookmarks allows them to work.
Rarely is the issue the configuration of the browser. Increasingly rarely, it is due to their temporary cache folder being full. It also sometimes happens that a Windows update changed their security settings of their browser, and their browser needs to be more permissive. This is pretty common for accountants who need to do extensive banking and electronic transactions online. What is interesting as well is that as Microsoft pushes people to the newer versions of their browser, sites will stop supporting older browsers. So then they get emails saying they need to upgrade their browser and then I get called.
Certainty what I am sharing are the differences. However as a home user, if you find that Chrome, IE, Firefox can’t make a website work properly, often just switching to another one will fix the issue. If not, then time to call your friendly neighborhood IT person. (Sorry Spidey)
