Compared to the world when most people were using Internet Explorer, today's web users have an embarrassment of excellent web browsers to choose from.

Choosing a different browser

Edge comes preloaded on Windows computers and doubles the market share of Firefox in the U.S. Mobile device users tend to use whatever comes preloaded on their device although you can download versions of Chrome, Firefox, and Edge for mobile devices.

Sometimes mobile users want to install the Chrome app, and instead install the Google app on their mobile phone, confusing Chrome with Google. Superficially, it looks the same, but lacks most of the features of a browser.

Testing your website

Although all these browsers are standards based, website owners still need to test their websites and web apps on several browsers and several devices to ensure there are no problems. It even happens that sometimes all browsers will work on desktop and not on mobile. For example, if a web app employs the drag and drop action and employs a "drag" listener, this will only work on desktops. A mobile device will only listen for "touch" actions. The developer needs to jump through a few hoops to emulate the same operations on mobile as on desktop.
