Checking for browser compatibility is important in the field of quality assurance. It is needed to maintain consistent website functions across different web browsers. Each browser interprets web standards differently. This can lead to variations in how a website looks and functions.
Testers prefer browser compatibility testing because it helps identify issues that may affect user experience. Test websites in different browsers to catch inconsistencies and errors that could negatively impact the user experience. Developers can fix problems early and design a more reliable website.
Note the target browsers and devices to test website in different browsers. Set up a testing environment and take care of some common issues. This blog will help you to perform browser compatibility testing. Know the tips for ensuring your website works well across all major browsers. You can achieve a consistent and high-quality user experience for all visitors with this guide.
Steps to Test Website in Different Browsers – Ensuring Compatibility
Below is a detailed guide to conducting cross browser testing to ensure compatibility:
Step 1: Define Your Testing Requirements
Identify the browsers and devices to test. Determine the scope of your testing.
- Target Browsers: Identify the most used browsers. Focus on major ones like Chrome, Firefox, Safari, Edge, and Opera.
- Target Devices: Consider different devices. Test on desktops, laptops, tablets, and smartphones.
- Browser Versions: Test on different versions. Include older versions still in use.
- OS Variants: Consider different operating systems. Test on Windows, macOS, Linux, iOS, and Android.

Step 2: Set Up Your Testing Environment
Set up a comprehensive testing environment. Use multiple methods to cover all bases.
- Installing Multiple Browsers: Download and install major browsers. Test directly on your development machine.
- Using Virtual Machines: Set up VMs for different OS and browser combinations. Useful for testing specific environments.
- Cloud-Based Testing Platforms: Access a wide range of browsers and devices. Cloud-based platforms often have pricing plans to help you save your budget. Using these platforms allows you to perform extensive Selenium testing across multiple browsers and devices. AI-driven test orchestration and execution platforms like LambdaTest offer a more scalable and cost-effective solution compared to setting up an in-house Selenium Grid. With an extensive online browser farm featuring over 3,000 combinations of browsers and operating systems, automation testing becomes more efficient. To switch from local to LambdaTest’s cloud Selenium Grid, you’ll need to update the infrastructure-related code in your test scripts.
Starting with Selenium testing on LambdaTest is easy– simply set up an account. The platform also provides a SmartWait feature to address synchronization issues in Selenium, improving the efficiency and accuracy of automated tests by performing actionability checks before interacting with webpage elements.
- Local Testing Tools: Use tools like BrowserSync. Test your website on different browsers within your local network.
- Browser Extensions: Install extensions like User-Agent Switcher. Quickly switch between different browsers and devices.

Common Compatibility Issues and Solutions
You may experience some common compatibility issues with your website. Below is a detailed to fix them easily and test website in different browsers:
CSS Flexbox and Grid Layout Issues
Flexbox and Grid layouts can render differently in various browsers. It’s essential to test website in different browsers and adjust for these differences.
- Browser Compatibility: Different browsers may support different Flexbox and Grid properties. Check compatibility tables before using specific features.
- Fallbacks: Provide fallback layouts for older browsers. Use float-based layouts as a backup.
- Autoprefixer: Use Autoprefixer in your build process. It adds necessary vendor prefixes to your CSS.
- Testing: Regularly test your layouts on all target browsers. Identify and fix layout issues promptly.
- Polyfills: Use polyfills for unsupported features. They help older browsers render new CSS properties.
JavaScript ES6 Feature Support
Not all browsers fully support ES6 features. You need to handle compatibility with older browsers.
- Transpilers: Use Babel to transpile ES6 code to ES5. This makes your JavaScript compatible with older browsers.
- Polyfills: Include polyfills for new ES6 features. Features like Promises need polyfills in older browsers.
- Compatibility Tables: Check compatibility tables for ES6 features. Know which features are not supported in which browsers.
- Conditional Scripts: Load polyfills conditionally based on browser support. This helps reduce unnecessary script loading.
- Testing: Test your JavaScript in all target browsers. Ensure all features work correctly across different environments.
Vendor Prefixes for CSS Properties
Different browsers require different vendor prefixes for some CSS properties. This can cause inconsistencies in styling.
- Autoprefixer: Use it to add vendor prefixes automatically. It helps maintain cross-browser compatibility.
- CSS Preprocessors: They help manage vendor prefixes more efficiently. Use preprocessors like Sass or LESS.
- Testing: Regularly test CSS in all target browsers. Identify properties that need vendor prefixes.
