While we consume content via apps, we use browsers too. From reading articles, bookmarking our favorite websites to sometimes booking tickets or shopping—browsers play a crucial role in how we spend time on the internet.

According to Statcounter, people primarily use six browsers that include Chrome, Firefox, Safari, and Edge. But this is not as straightforward as it sounds. When you consider browser versions, there are different versions for mobile, web, and also OS. For instance, let's look at the following graph on Browser Version Market Share by Statcounter

Globally, around 35.06% of users use Chrome for Android, whereas 15.2% use Chrome 89.0. As you can notice, there are multiple other versions, which brings us to a pivotal question — how important is it to perform browser testing? 

Well, it's quite important if we take into account the fact that our users consume content via browsers on the web, mobile, and on devices with various versions of OS, including outdated versions. For our product to perform uniformly and as intended across different browsers and their versions, browser testing is performed. 

In this article, we'll explore the best tools for performing browser testing. Before we proceed, please check out our article on browser testing and when to start
