The first step taken by Microsoft on improvements is on redesigning the network tools so that the developers can get a cleaner experience. Next, Microsoft’s team also added a Start and Stop toolbar button to provide more flexibility to developers while dealing with HTTP-based network traffic.

There is also a new button called “Content type filter” which has been added to allow developers to put the filter and get only the type of traffic which is desired. So by this you can skip many unrelated network calls and at the same time get relevant information regarding the type and number of network errors, number of requests, response data transfer sizes, and download times etc.

You can also export and keep a track of all the information in a JSON HAR file.

Notable F12 Developer Tools enhancements for Microsoft Edge

The lists of enhanced items that are included in the New Microsoft Edge are as follows:

  • Always refresh from server: This functionality ensures that you are testing against the latest version of a resource from the server instead of outdated one.
  • Clear cache and cookies: This makes sure that your browser’s cache is clear before loading the next page and you can clear the cookies with the shortcut without even going to browser settings
  • Clear session– You can use clear session button to clear any network traffic information recorded during the session
  • Clear entries on navigate– With this feature you can only focus on resources that were loaded during the last page refresh or navigation. You can even compare this with the last session just by turning this feature off
