“We’re not supporting new web standards for it and, while many sites work fine, developers by and large just aren’t testing for Internet Explorer these days. They’re testing on modern browsers,” said Chris Jackson, worldwide head of cyber-security at Microsoft’s Windows division, in the blog post. Jackson said that developers now no longer test on the legacy Web browser, but instead use “modern browsers”. While many of the users these days either use Google Chrome or Mozilla Firefox, some firms still depend on Internet Explorer for web apps that have been built using the old infrastructure. The security expert also explained why companies need to be aware of their “technical debt”, as they are paying for extended support of older software. Responding to the user comments section of his blog post, Jackson clarified that he’s not influencing people to never use Internet Explorer. “My concern is that to accommodate apps that do need IE, we use it for everything. We want you to use IE for the sites that need it — what I’m trying to say here is that I hope you don’t use it for everything else,” he said. “The candle is burning from the other side with that approach — now your new sites break while keeping your old sites fixed. I’d like to craft a solution where both your old sites and your new sites work.” Launched in 1995 with Windows computers, Internet Explorer, was one of the most widely used web browsers, that once held 95 percent of the market in 2003. In 2015, Microsoft had announced that Microsoft Edge would replace Internet Explorer as the default browser on its Windows 10 devices. However, Edge has struggled to make a mark due to stiff competitors like Chrome, Firefox, and Safari. Microsoft recently announced that it will be ending support for Internet Explorer 10 on January 31, 2020.
