The latest Canary build of Microsoft Edge on Windows has a new tool that can detect performance issues in the browser and recommend mitigating actions. Slow and laggy browsers are a massive problem and can often take a huge toll on productivity. While most browser vendors promise a super-fast experience, reality is often very different.

Edge is Microsoft‘s default web browser in Windows 11, but was originally rolled out for Windows 10 in 2015 when it replaced the reviled Internet Explorer. In its Chromium avatar, the Edge browser is also available on Windows 7 and Windows 8/8.1, but does not support Vista or earlier editions of Windows. While the browser was originally based on Microsoft‘s own EdgeHTML engine, it has since switched over to the open-source Chromium, making it compatible with extensions on the Chrome web store.

Called ‘Performance Detector,’ the new feature is currently only available in the Canary version of Microsoft Edge. The tool is designed to detect any issues caused by unnecessary tabs or third-party extensions that may be hogging system resources, resulting in a sub-par performance. The tool will also recommend actions to fix any performance issues it detects, although it is unclear how that will happen. The MS Edge Settings page explains, “When this is on, the browser detects tab performance issues and recommends an action to fix,” according to Windows Latest, The feature is switched on by default, but users can toggle it off if they want.

Performance Detector Can Be Easily Enabled/Disabled

To enable or disable the Performance Detector tool, the latest Canary version of Microsoft Edge will need to be downloaded and installed. Then launch the browser, click on the three-dot menu button at the top-right corner, and select ‘System and performance‘ on the left sidebar. Now scroll down a little to find and toggle the switch next to ‘Performance detector‘ to enable or disable the feature. Even though the Performance Detector tool is currently available in the Canary version of Microsoft Edge, there’s currently no word on when it will receive a wider release via the stable version.

Apart from Performance Detector, the Edge browser also offers another notable ‘Efficiency Mode’ tool that helps extend the laptop’s battery life by minimizing the amount of power and system resources the browser uses. It does so in a variety of ways, including putting background tabs to sleep after a period of inactivity, and fading sleeping tabs in order to reduce memory and CPU usage. Microsoft claims that the feature not only improves power efficiency, but overall helps the PC perform better when its Edge browser is in use.
