Therefore, you need to test your web applications rigorously across different devices. This includes both desktop and mobile devices.

• Performance Variations: Every browser has its unique rendering engine. They render web applications differently. This leads to a difference in performance metrics. The web application’s load times and responsiveness change from one browser to another. Therefore, you must identify performance issues and optimize them. This will allow a seamless user experience across all browsers.

• Feature Support: With the advancement in technology, all browsers are not capable of supporting the latest technologies and features. Therefore, a developer needs to implement fallbacks and polyfills. This ensures the correct functioning of web applications on older browsers.

• Debugging Difficulties: There are several browser-specific issues. Debugging these issues is challenging. You need to have a deep knowledge of how browsers interpret web technologies. You also need to understand which feature of your web application will be interrupted differently by which browser. Based on these you should access tools that will facilitate efficient debugging.

• Automation Challenges: Automation challenges are another blockage to providing browser compatibility. Automated test scripts are complex. Test script creation and maintenance require time. Further, there may be a difference in browser behavior which can lead to flaky tests. These falkiness are difficult to debug and maintain.
