Note that, a browser may crash or shows an error after enabling the flags. But, you can disable and reset the flags any time.

However, most of them are working on Windows and macOS platforms. But, some functions are only available for Windows users.

1. Show Autofill predictions

If you regularly fill out the forms on a web browser, then this function is useful for you. While filing the forms or signup for an account, this Edge flag can auto-fill your details i.e. name, email, address, phone number, and other details. It will save you time.

2. Secure DNS lookups

You can enable DNS over HTTPS by enabling secure DNS lookup. This function encrypts your communication with websites on the internet because it automatically uses HTTPS security on most of the sites.

After enabling it, the Edge browser will try to use an HTTPS connection to look up the websites.

However, there are numerous extensions available for this, but, you don’t need any extension, because the Edge browser gives a built-in functionality for this.

Secure DNS lookup may break the website. If you found a problem with any website, you may need to disable it to view the site.

3. Focus Mode

With this flag, you can switch any tab to the focus mode. This will open the tab in the new window with minimal UI.

This feature may be helpful for you while reading from the web page.

6. Enable lazy image loading

Normally, when you open any web page, the browser loads all web page data (including text, JavaScript, images, CSS, and other) from the webserver. If the web page contains more than 15 images, it downloads all images whether you will scroll down or not.

Lazy image loading defers offscreen images and shows the images when needed i.e. when you scroll down. This Edge flag is useful for both server and client end. At the client end, it will save your bandwidth or data, because images will not load until you scroll down near them. At the server end, it will help to reduce the unwanted load and bandwidth also.

However, many websites and blogs enable this feature from the server end. But, most of the websites aren’t offering this feature. So, now you can also enable lazy image loading from your browser.
