Microsoft has exerted much effort with its new browser: Microsoft Edge. And it seems that everything has paid off. This improved browser has plenty of amazing features that it makes a worthy competitor of Microsoft Firefox and Google Chrome.

An Overview of Microsoft Edge

Since its inception, Microsoft Edge has had several updates. Its newest version is what many call the Chromium browser.

Now, why “Chromium?” This is because it can run and support extensions that were originally designed for Chrome users. These extensions include in-browser games, screen readers, productivity tools, and a lot more.

This is already on top of the existing extensions available on Microsoft Store. So, if you have a feature you wish Edge has, then it’s safe to assume that there’s an extension for it.

Expert Tip: For smoother PC performance, consider using a PC optimization tool. It handles junk files, incorrect settings, and harmful apps. Make sure it's right for your system, and always check the EULA and Privacy Policy.

As with Google Chrome, your settings on Microsoft Edge can be saved. As long as you have a Microsoft account, you can sync your browsing history, passwords, bookmarks, extensions, and more. This also means that if you open Microsoft Edge on another computer, you can still access your browsing data in an instant.

If you wish to give this browser a try, feel free to download it from Microsoft’s official website.

Enable and Disable Sleeping Tabs in Microsoft Edge and Other Features

We’re not forcing you to choose Microsoft Edge, but we encourage you to give it a try. To help you make an unbiased choice, here are some of its best features:

Fast Speed

Instead of upgrading Internet Explorer, Microsoft built Edge from scratch, allowing them to add features that most internet users need: interactions, applications, and diverse content types. Even with all these additions, Edge does not fail in terms of speed. In fact, it’s as fast as its known competitors, Firefox and Chrome.

Personalized Content Feed

When you open Edge, its default page will display a selection of videos, news stories, and other pieces of information tailored to your interests and preferences. This is called My Feed.

Sleeping Tabs

Sleeping Tabs is another feature of Microsoft Edge you dare not miss. It is designed to improve your system’s performance and your device’s battery life. Once enabled, it allows you to save your system resources as it puts your background tabs into idle mode. By default, this feature is disabled. However, you can easily enable and disable them by following the instructions we have provided in the next section.
