Top Browsers For Cross Browser Testing In 2023

We might have commonly observed that some of the applications or websites we visit display perfectly fine on some browsers and in some it does not.

In such scenarios, we just think that the application or website is broken and we end up using that particular application or website.

This rendering clarifies the compatibility of an application with different browsers.

It is important to understand the reason for such a mishap.

When a developer builds a new application with a lot of hard work and before the release, it looks perfectly fine and functions great for them.

It is certain that the applications that they built work the way it was intended in their machine or the browser they have tested in.

But it may not work the same as it has not been tested for visual compatibility in others.

And this is the reason for the application to be in trouble and non-presentable in other systems or browsers.

This particular trouble is known as a cross-browser compatibility issue which is one of the biggest concerns for the developers that they are dealing with today.

With the advancement of technology, there are several options available for users to visit sites from different browsers and devices.

They are not restricted to using any specific browser to access the application.

So it is not just enough to make the application work on only one of the browsers.

It is critical to ensure that applications are compatible with different Operating Systems, devices, and multiple browsers like (Chrome, Safari, Firefox, Internet Explorer, etc).

As it directly affects the revenue and reputation of the organization.

Cross browser testing is the only way to know that the application released is providing the user’s needs and whether it is performing the way it was intended to perform.

As its name implies, cross-browser testing means testing an application or website across browsers, devices, Operating Systems, and in different screen resolutions.

It is to ensure that it meets the expectations, standards and works consistently without any dependencies or quality compromise.

Cross-browser testing applies to both mobile and web applications.

After the above discussion let us discuss here in short why an application renders differently in different browsers?

Each browser works on different engines and different language frameworks making it interpret the information differently.

As some browsers may lack the feature that the application is trying to show.

This makes the application appear as different or broken on that browser.

Twining them with different devices and operating systems gives an unlimited number of ways to experience the application.

This gets even more difficult when the machines are limited and developers can see the end result in a limited configuration only.

In order to overcome this, the developers are required to perform cross-browser testing either in an in-house device lab or they need to deploy to a third-party cloud testing platform like LambdaTest.

Selecting the right browsers for testing

The above-provided knowledge makes good sense that testing websites or applications on different browsers and devices are very important to successfully scale the business and stay relevant in the market.

The existing number of browsers, devices, and Operating Systems makes it a challenge to test on every browser and OS combination.

In such cases, the realistic goal could be to maximize website reach within the targeted market.

Different internet users use various browsers with different combinations of OS and devices so they all must be compatible with the application for user satisfaction.

Hence to do this you just need to know and lock down the most popular browsers and versions among the users.

The discussion below will help you decide to choose the suitable browser to perform cross-browser testing.

Selection based on popularity

Select the most popular and globally used common browsers such as Google Chrome, Firefox, Microsoft Edge, Safari, Opera, and more.

By the way, pick platforms like Windows, Android, and iOS.

This maximizes the reach that the users preferably use.

By adding these options you can go for your cross-browser testing.

Selection based on analysis

By examining the applications traffic stats captured by Google Analytics or other online analytics tools and breaking them down by the customers’ choice of browser and platforms.

The purpose of this is to find out:

  • Which browser and OS combinations are generally used by the targeted audience.
  • On what devices the application is generally used.

These two aspects will help to filter down the web browser choice and the use of the different electronic devices.

Based on these findings, the finishing step will be to pick the browser and proceed to test the application.

‍Top browsers for cross-browser testing

To ease your testing process here are some suggestions of top browsers for cross-browser testing that will help you in your browser listing process for compatibility testing of your application.

Let’s get started…

Google Chrome

The Google Chrome market share is continuously rising.
