The digital landscape continues to grow rapidly, presenting web developers with novel challenges. Compatibility with older browsers is one enduring barrier in this age of cutting-edge technologies and swift advances. Even with the launch of the contemporary web browser, Internet Explorer continues to impact the web significantly and is still one of the difficulties that bridge builders typically encounter.
Internet Explorer online has been one of the most widely used web browsers for over ten years, particularly in corporate and enterprise settings where legacy systems are still often used. It does not support contemporary web standards either because developers still have to work really hard to push the limits of what they can do. Every time the consideration of various versions and configurations adds complexity, integration issues arise, customer happiness drops, and the business becomes less competitive.
This blog post will explain how to test Internet Explorer online. Let’s get started!
Recognizing the Legacy Issue
Internet Explorer is still present in the browser situation in 2024, although not as prominently as it did during the height of its popularity. Despite losing market dominance, web developers still regard it highly because of its extensive usage in a few niche industries. Despite the introduction of more sophisticated browsers, many users still use Internet Explorer, particularly in business and specialized settings, despite stronger competition from other browsers.
For web developers, browsing through IE’s compatibility brings up various issues. One of the primary issues is that the rendering engine needs to be updated and able to support many of the new features and standards for the web. As a result, there won’t be enough consistency in the way that browsers look and function, which will push developers to use workarounds and hacks to keep things somewhat uniform.
Furthermore, Internet Explorer’s fractured architecture makes connectivity issues more complicated. Among the most challenging elements is the widespread use of different IE versions, ranging from IE8 to IE11. The developers have to cope with varying degrees of behavior and support. Consequently, this adds to the complexity of the testing and debugging procedures. Since Internet Explorer is an integral part of the Windows operating system and adds even more cross-platform compatibility, this fragmentation applies to operating systems.
In addition to causing technical problems, Internet Explorer compatibility problems have a negative impact on user experience and business goals. When a product or website is made exclusively for Internet Explorer, a significant percentage of users may not be able to access it, which can lead to irritation, lower user engagement, and, ultimately, revenue loss.
Furthermore, a business that refuses to be compatible with Internet Explorer may face a wide range of consequences. Delegating the installation of Internet Explorer may result in failure to comply with regulations or contractual commitments, which may have legal ramifications or violate contracts. Additionally, failing to address this results in adoption being hampered, and market reach is limited, if not entirely eliminated, in commercial environments where Internet Explorer is still commonly used due to legacy applications.
Why Online Testing Is Important
The Benefits of Online Testing Tools for Older Browsers
It cannot be overstated in the continually changing online world that thorough testing of legacy browsers, especially Internet Explorer, is crucial. The following benefits of using online testing platforms are especially relevant when considering older browser support:
Accessibility:
Online testing platforms do not require manual configurations or virtual computers; instead, virtual browsers spring up, including older versions of Internet Explorer. By being accessible, the testing process may be made easier and faster iteration and debugging can be supported.
Cost-Effectiveness:
To evaluate Internet Explorer’s compatibility with different browsers, it can be pretty costly and time-consuming to configure and maintain the infrastructure, which consists of numerous real and virtual machines. Online testing solutions provide an inexpensive alternative by adapting the solution to the changing needs of various browser versions and settings that allow for the avoidance of costly infrastructure setup.
Scalability:
In the same way, as projects expand in size and complexity, so does the need to test them in various browser contexts. Online testing platforms offer scalability since they let developers expand their testing procedures without requiring them to adhere to extra infrastructure requirements or find and share resources.
Real-Time Feedback:
Online testing tools enable development teams to collaborate and provide real-time feedback, making identifying and resolving compatibility issues simple. Developers may expedite the debugging process and achieve a more seamless development workflow by providing robust tools such as instantaneous result reading and diagnostics.

Strategies for Testing Internet Explorer Online
The fragmentation caused by the Internet Explorer ecosystem, which spans from IE 8 to IE 11, is a big issue for developers who want to provide a similar experience across all browsers:
Prioritize Target Versions:
Describe the Internet Explorer versions and how they relate to the user demographics and project needs. The most widely used versions should receive the majority of resources, while legacy users’ needs must be met by maintaining backward compatibility.
Make Use of Online Testing Platforms:
Use AI-powered test orchestration and execution platforms like LambdaTest to access various Internet Explorer versions for manual and automation testing. Conduct thorough testing on several versions to identify and fix any compatibility issues that may arise from one version to the next.
Employ Feature Detection:
Utilize feature detection methods such as Modernizr and conditional comments to identify and manage feature variations across different versions of Internet Explorer. Developers are able to provide fallbacks or other versions of features that aren’t compatible with older versions of the software because of this technique.
Responsive Design and CSS Compatibility
A crucial element in ensuring that the user has a pleasurable and visually appealing surfing experience is the compatibility of responsive design and CSS across Internet Explorer versions:
- Implement Vendor Prefixes:
When implementing CSS properties, use vendor prefixes (-ms-, -webkit-, -moz-, etc.) to ensure consistency between Internet Explorer versions. Examine CSS layouts carefully in all project versions to ensure inconsistent rendering is suspended and corrected.
- Shims and Polyfills:
To emulate the capabilities of the most recent version of Internet Explorer, apply shims and polyfills that imitate contemporary HTML and CSS features, such as Flexbox and Grid layout polyfills. This allows developers to employ sophisticated layout strategies, which simultaneously necessitate compatibility with earlier browser versions.
- Progressive Enhancement:
Use a progressive approach while designing CSS, applying fundamental layouts and styles to all browsers and gradually adding expanded features for more recent browsers. By doing this, Internet Explorer—which might not support more sophisticated CSS properties—can degrade more smoothly.
JavaScript and DOM Manipulation Testing
In order to maximize the interactivity and utility of online applications, JavaScript and DOM manipulation are crucial because they allow for the following:
- Cross-Browser Testing:
Use local testing environments or Internet testing platforms to thoroughly verify JavaScript functionality on various Internet Explorer versions. Be aware of how different versions affect how DOM handling and JavaScript engines behave.
- Use Feature Detection:
Use feature detection libraries (like Modernizr) or feature detection techniques (like typeof) to identify programmable JavaScript functionality and detect browser capabilities. This is a very real possibility. As such, it enables developers to offer fallbacks or substitute implementations for features incompatible with Internet Explorer versions prior to that one.
- Transpilers and Polyfills:
Make sure they are compatible with older versions of Internet Explorer by using transpilers and polyfills, such as Babel or Polyfill.io, to fill in the gaps in JavaScript compatibility. This motivates developers to utilize the most sophisticated JavaScript features while maintaining backward compatibility with outdated browsers.
Techniques for Debugging and Troubleshooting
Sophisticated tools and a systematic approach are needed for Internet Explorer compatibility issue troubleshooting and bug detection. Take into account these methods:
- Developer Tools:
Use the built-in Developer Tools in Internet Explorer to inspect HTML, CSS, and JavaScript to address compatibility issues. To pinpoint the cause of issues, keep an eye out for rendering irregularities, console errors, and network requests.
- Compatibility Mode:
To determine which specific compatibility difficulties are caused by this browser version, test websites and web apps in Internet Explorer’s compatibility mode to emulate the version of the old browser. Use document mode and compatibility settings as necessary to fix any rendering or functioning issues.
- User-Agent Switching:
Try compatibility on different configurations by imitating older versions of Internet Explorer with user-agent switching tools or browser plugins. As a result, in order to identify and fix bugs, developers can simulate the user experience for a specific browser version or environment.
Emulation vs. Virtualization: Choosing the Right Approach
Developers frequently find themselves at a decision between emulation and virtualization while doing Internet Explorer compatibility testing online:
- Emulation
Emulation combines their capabilities to run multiple browser versions within a single browser. Emulation solutions, such as Microsoft Edge’s IE mode or some of virtualization features, make testing several versions at once easy and efficient. Although emulation can’t perfectly replicate the subtle differences between every browser’s rendering engine and JavaScript implementation, it can identify the reasons behind any discrepancies in test results.
- Virtualization
By running several instances of Internet Explorer in virtual machines or containers, virtualization enables more accurate replication of the functionality of every browser version. Virtualization technologies such as VMware and VirtualBox provide additional control and customization capabilities, allowing users to test specific browser settings.
On the other hand, virtualization requires more time and resources than emulation. Thus, it’s not a clear-cut answer for repeated testing cycles.
