Difference Between Internet Explorer and Microsoft Edge

Do you want to know the difference between Internet Explorer and Microsoft Edge? You’ve come to the right place.

In this article, we’ll take a look at the differences between the two browsers in terms of compatibility, security, performance, interface, customization, sharing, autofill, voice search, and 4K video support.

We’ll also discuss which one is the better choice for various uses.

Get ready to make an informed decision about which browser is best for you.


When it comes to compatibility, you’ll notice the biggest difference between Internet Explorer and Microsoft Edge right away. IE relies on ActiveX controls, binary behaviors, and VBScript, making it much less flexible than Edge. Edge is built on the same Chromium engine as Chrome and uses HTML5, CSS, and JavaScript. This makes Edge more compatible with modern web standards.

IE can still render most websites, but its age shows. It can take longer to load webpages, and videos and animations may not play correctly. Microsoft Edge, on the other hand, runs faster and more efficiently. It also supports modern web technologies, such as WebGL and WebAssembly, as well as extensions.

With IE, you may also find that certain websites don’t work as they should. This is because IE isn’t always kept up to date with the latest web standards. Edge, however, always has the latest and greatest web technology built in. This ensures that websites always display correctly and that your browsing experience is smoother.


When it comes to security, you’ll notice a significant difference between Internet Explorer and Microsoft Edge.

Microsoft Edge is designed to help protect you from malicious attacks while you’re browsing the web. It features built-in security protections, such as SmartScreen Filter, which helps prevent you from visiting malicious websites, and Windows Defender SmartScreen, which helps protect you from downloading malicious files. Additionally, Edge comes with support for the latest web standards, ensuring the latest security features are available.

Internet Explorer, on the other hand, is much less secure. It lacks the same level of security features as Edge, and is more prone to malicious attacks. Additionally, it’s no longer supported by Microsoft, and is missing support for many of the new web standards. This makes it much less secure than Edge and more vulnerable to malicious attacks.

Therefore, when it comes to security, the difference between Internet Explorer and Microsoft Edge is clear. Microsoft Edge provides you with the latest security features, while Internet Explorer lacks these protections and is more vulnerable to malicious attacks. To ensure the best possible security, it’s recommended to use Microsoft Edge for browsing the web.


How quickly does each browser load? Speed is an important factor to consider when comparing Internet Explorer and Microsoft Edge.

Internet Explorer has been around for some time and while it was once the market leader, its performance has been diminished by the introduction of more modern browsers. As such, loading times are noticeably longer than those of some of its competitors.

On the other hand, Microsoft Edge is a newer browser designed for Windows 10 and has been optimized for improved loading speeds. It can render pages faster than other browsers, including Internet Explorer, making it a better choice if performance is a priority. Microsoft Edge also has a native rendering engine that helps to improve responsiveness, which further improves its loading times.

When it comes to performance, Microsoft Edge is the clear winner, offering faster page loading times and a more responsive experience.


Moving on from performance, another key difference between Internet Explorer and Microsoft Edge is their interfaces.

Internet Explorer’s interface has an old-fashioned design, with its tabs and menus easily accessible at the top of the browser.

Microsoft Edge, on the other hand, has a cleaner, more modern design. Its tabs and menus are hidden from view until you choose to open them, giving more focus to the web page you’re viewing.

Another difference between the two is that the Edge browser has a “reading view” that strips away ads and other distractions, making it easier to read articles without getting sidetracked. Additionally, Edge has a “collections” feature that allows you to save and organize webpages, images, and links into collections for later use. These features aren’t available in Internet Explorer.

As such, Edge has a more user-friendly interface, allowing for a better overall browsing experience.


You can customize your experience with both Internet Explorer and Microsoft Edge, but in different ways.

Internet Explorer allows you to customize the look of your browser, such as changing the color scheme, background, or font size. You can also add new features to the browser by installing add-ons or extensions.

Microsoft Edge, however, doesn’t allow you to customize the look of your browser. Instead, you can customize the preferences of the browser. You can set the default search engine, turn on or off tracking protection, and opt to allow or block sites from storing cookies. You can also install extensions from the Microsoft Store.

Both of these browsers offer a wide range of customization options, giving you the opportunity to create a personalized browsing experience.

Web Standards

When it comes to web standards, Internet Explorer and Microsoft Edge differ in their approach. Microsoft Edge is built on the latest web standards, making it more secure, faster, and more compatible with websites. Edge is compatible with HTML5, the latest version of the HTML standard, and also supports a broad range of existing web standards, like CSS3 and ECMAScript 2015. This means Edge can display and interact with websites in a reliable and consistent manner.

Meanwhile, Internet Explorer isn’t built on the latest web standards, and doesn’t support some of the features available in Edge. Instead, it relies on older web standards, which can be incompatible with some websites. This can lead to sluggish and unreliable performance, as well as security risks.

Therefore, Edge is the better choice for users looking for an up-to-date browsing experience.


Though both Internet Explorer and Microsoft Edge are designed to protect user privacy, they differ in the level of security they provide.

Microsoft Edge is designed to offer superior privacy settings compared to Internet Explorer. For instance, Edge includes a tracking prevention feature that blocks third-party trackers from collecting your browsing data. It also offers a “InPrivate” browsing mode which allows you to browse the web without leaving any trace of your activity on the device.

Internet Explorer, on the other hand, doesn’t offer the same level of privacy as Edge. While it does have a “InPrivate” mode, it doesn’t have the same level of tracking prevention as Edge. Additionally, Internet Explorer doesn’t support the “Do Not Track” feature which lets you opt-out of being tracked by websites.

For those who value their privacy, Edge is the better choice as it offers more secure and comprehensive privacy settings. It also offers more comprehensive tools for managing and controlling your privacy, such as allowing you to clear your browsing data or setting up a password for your browser. In comparison, Internet Explorer doesn’t offer the same level of control.

Ultimately, both Internet Explorer and Microsoft Edge offer a degree of privacy protection, but the level of security and control offered by Edge makes it the superior choice for those who value their privacy.


When it comes to extensions, Microsoft Edge has the clear advantage over Internet Explorer. Edge allows you to add a range of extensions from the Microsoft Store, while Internet Explorer does not. This means that you can tailor Edge to your needs with the addition of extra features, such as ad blockers and password managers. Also, Edge’s extensions are regularly updated to ensure compatibility with the latest version of the browser.

Internet Explorer, on the other hand, doesn’t have the same level of support for extensions. While there are some add-ons available, they’re few and far between. Additionally, they’re generally not updated to support the latest version of the browser, making them unreliable and potentially unsafe to use.

In addition to this, Edge has far more options for customizing its appearance. It enables you to select a theme, change the background, and even select a color scheme. Internet Explorer, in contrast, has limited options for customizing its appearance.

Mobile Support

While Edge may have the clear advantage in terms of extensions and customizing its appearance, Internet Explorer is much better suited for mobile support. It offers superior options for mobile users that don’t exist in Edge.

Microsoft Edge doesn’t support any mobile operating systems other than Windows 10 Mobile. Internet Explorer, on the other hand, supports iOS and Android, allowing mobile users to access the internet from a variety of devices.

Additionally, Internet Explorer is more reliable when it comes to compatibility with websites and services, as it’s almost universally supported. This isn’t the case with Edge, which is still a relatively new browser.

Finally, Edge isn’t optimized for mobile use, whereas Internet Explorer is designed to be used on mobile devices, providing a better, more streamlined experience for users.

Browsing Data

Moving on, when it comes to browsing data, both Internet Explorer and Microsoft Edge offer users different levels of control.

Internet Explorer allows you to limit the amount of data stored on your devices by setting up InPrivate Browsing. This mode prevents history, form data, cookies, and usernames and passwords from being stored.

Microsoft Edge, on the other hand, offers a feature called Tracking Prevention which allows you to select the level of tracking prevention you’d like to use. With this feature, you can choose between basic, balanced, and strict settings. The higher the level of tracking prevention you choose, the more data that will be blocked from being stored.

It’s important to note that both of these browsers provide users with the option to clear their browsing data. This is a great way to ensure that no data is stored on your devices, thus providing you with added security.

Developer Tools

One of the key differences between Internet Explorer and Microsoft Edge’s developer tools is their respective possessive capabilities. Microsoft Edge is equipped with a modernized version of Internet Explorer’s F12 Developer Tools, as well as additional features for web developers.

These tools include a DOM explorer, a console, a debugger, and a network inspector. With the DOM explorer, you can browse the elements of a page, view their properties, and access the source code. The console provides a JavaScript debugging interface and is capable of displaying various types of messages, such as warnings, errors, and log messages.

The debugger allows you to pause code execution at breakpoints and inspect the values of variables. Finally, the network inspector gives you the ability to view the HTTP requests that are sent by a webpage.

While Internet Explorer’s developer tools provide basic functionalities, Microsoft Edge is equipped with advanced capabilities, such as the ability to debug JavaScript code and inspect webpages with an improved user interface.

Password Management

When it comes to password management, Microsoft Edge provides superior protection compared to Internet Explorer. Edge stores user passwords in its secure vault, which is encrypted and protected with two-factor authentication. Internet Explorer, on the other hand, stores passwords in plain text, leaving them vulnerable to hacking.

Edge also allows users to sync their passwords across devices, allowing easy access to their accounts on any device. Internet Explorer doesn’t offer this same level of convenience.

When users save passwords in Edge, they’re protected by additional security measures, such as Windows Hello, which requires a face, fingerprint, or PIN to unlock the vault. Internet Explorer doesn’t offer this level of protection.

Edge also has an intelligent password generator, which makes it easier to create complex and secure passwords. Internet Explorer, however, doesn’t have this feature.

Cortana Integration

Continuing from password management, Microsoft Edge also has the added advantage of Cortana integration, allowing users to access search results, reminders, and other features with voice commands.

Cortana is a digital assistant created by Microsoft and is integrated into many Microsoft products, including Edge. With Cortana, users can easily search the web, set reminders, and access other features with voice commands.

Cortana is a great tool for anyone who wants to quickly access information or set reminders without having to type out a search query or manually set an alarm. Additionally, Cortana is available in multiple languages and can be personalized to your preferences.

For users who are always on the go, Cortana also has a mobile app, allowing you to access its features while away from your computer. Cortana can also be used to access information from Microsoft Office and other Microsoft products.

This makes it easy to access important documents, spreadsheets, or other files with just a few voice commands. Overall, Cortana integration in Microsoft Edge is a great addition to the browser that makes it easier for users to access information quickly and with minimal effort.

Ad Blocking

Compared to Internet Explorer, Microsoft Edge offers significantly more control over ad-blocking.

This allows users to customize how they interact with ads, giving them the power to decide which ones they want to see.

Microsoft Edge has built-in features that enable users to block ads from certain websites or block all ads from showing up in the browser.

Additionally, users can control which types of ads they want to see, such as those related to their current search terms or those that provide discounts or savings.

Furthermore, users can choose to block ads based on specific categories, such as those related to gambling, alcohol, or drugs.

These features make Microsoft Edge a much more tailored ad-blocking experience, allowing users to have more control over how they interact with ads online.

Web Notes

You can easily take notes on webpages you visit with Microsoft Edge, something you can’t do with Internet Explorer.

With Edge, you can use the Web Notes feature, which allows you to highlight text and add notes or comments to the page.

To use this feature, open a web page in Edge and click the pencil icon at the top of the page. This will open a toolbar that allows you to select text and add notes.

When you’re finished, your notes and comments will appear in the sidebar on the right side of the page. You can also save your notes for future reference.

This makes it easy to quickly take notes for research or other activities without having to switch back and forth from a separate program.

With Internet Explorer, you don’t have the same ability to take notes directly within the browser.

You can still take notes on web pages, but you must open a separate program like Word or Notepad and copy and paste your content over.

This can be cumbersome and time consuming.

With Microsoft Edge, you can take notes quickly and easily without having to leave the browser.

Reading View

Enjoy a distraction-free reading experience with Microsoft Edge’s Reading View feature, unavailable in Internet Explorer. This feature strips away all unnecessary clutter, leaving just the text and images of the article intact. It also supports multiple languages, allowing you to switch the language of your page with a single click. Furthermore, Microsoft Edge’s Reading View can automatically adjust the font size and contrast of the page to make it easier to read. This is especially useful when reading longer articles.

Microsoft Edge’s Reading View feature also has a built-in dictionary that can be used to look up words with a single click. It also provides a summary of the article, making it easier to quickly get an overview of the content. Plus, you can highlight passages or add notes as you go along.

In comparison, Internet Explorer doesn’t have a Reading View feature. The closest thing it offers is a Text Size option, which can be used to manually increase the font size of a page. However, the text size can only be increased in small increments, and there’s no way to customize the page’s contrast or font size. Additionally, Internet Explorer doesn’t have a built-in dictionary or a summary feature.


Often, you’ll find it easier to share webpages between devices and people using Microsoft Edge than with Internet Explorer. With Edge, you can easily share a webpage with your contacts simply by clicking the Share button in the top right-hand corner. This allows you to quickly and easily share to Twitter, Facebook, and other applications. Additionally, you can share the webpages you’re currently viewing with other Windows 10 users. Furthermore, Edge users can also share their current web page via a QR code, which can easily be scanned by another device.

Internet Explorer, on the other hand, has very limited options for sharing webpages. You can only share a page via email or via a link. It’s not possible to share to social media, which makes it difficult to share a webpage with a wider audience. Additionally, because Internet Explorer is no longer supported, it isn’t possible to share a webpage with other Windows 10 users.


Filling out forms quickly and accurately can be done more easily with Microsoft Edge than with Internet Explorer. Autofill is a feature of Microsoft Edge that makes completing forms much simpler. With Autofill, your personal information is securely saved in the browser, so that you don’t have to type it all out every time. It can save your name, phone number, email address, and even credit card information for easy, one-click access.

Internet Explorer doesn’t offer Autofill, which can be a drawback when it comes to completing forms quickly and accurately. This means that users must manually type in their personal information each time they need to fill out a form, which can be quite tedious. It also adds a bit of risk, as users must trust that the website they’re using is secure before they enter in their sensitive information.

Autofill is an incredibly useful and secure feature, and Microsoft Edge is the only browser that offers it. If you’re looking for a fast and efficient way to fill out forms with accuracy and ease, Microsoft Edge is the way to go. It will save you time, and keep your personal information secure.

Voice Search

Another way Microsoft Edge stands out when it comes to form-filling is its voice search feature. With this feature, you can utilize the power of voice recognition to fill out forms — all you have to do is speak the information you want to enter. It’s a great way to save time and simplify your online experience.

Microsoft Edge’s voice recognition technology is powered by Cortana, the company’s digital assistant. Cortana is able to understand natural language and can help you complete tasks you’d normally do manually.

The voice search feature of Microsoft Edge is more advanced than similar features offered by Internet Explorer. With Internet Explorer, you’re limited to searching the web using keywords. With Microsoft Edge, you can use voice commands to fill out entire forms. This is especially useful for users who want to complete forms quickly and without typing out every single field.

The voice search feature of Microsoft Edge is also more accurate than Internet Explorer’s. Microsoft Edge uses advanced natural language processing algorithms to accurately understand and interpret what you say. This means that you can trust the information you’re entering into forms is accurate and secure.

4K Video Support

Building on the enhanced form-filling capabilities of Microsoft Edge, users can now enjoy the convenience of K video support. This feature allows you to watch videos in K quality on supported websites with Microsoft Edge, giving you a superior viewing experience than with Internet Explorer.

With K video support, you’ll be able to watch videos in higher resolution, with improved clarity and sharper details. Additionally, K video support offers smoother playback with less buffering and faster loading times. This is made possible with the use of the latest H.264 video codec, which is able to compress videos to smaller sizes while still providing the same high-quality experience.

Furthermore, K video support also allows you to watch videos in multiple formats without needing to install extra plugins. This makes it easier for you to watch videos on different websites without having to worry about compatibility issues.

Microsoft Edge also allows you to adjust the settings for each video, giving you more control over the quality of the videos you watch. So, with K video support and the other features of Microsoft Edge, you can enjoy a superior browsing experience than with Internet Explorer.


When it comes to web browsing, there are both pros and cons to using Internet Explorer and Microsoft Edge.

While Internet Explorer is compatible with many older websites and plugins, it doesn’t offer the same level of security, performance, or customization that Edge does.

Edge also has features like voice search, 4K video support, and autofill that Internet Explorer doesn’t.

Ultimately, it comes down to what you value most in your web browsing experience.
