In their own words
Microsoft Edge
Microsoft Edge is a free web browser for desktop and mobile devices, available on Windows, macOS, Linux, iOS, Android, and the web. It uses Chromium, supports extensions, and includes ad blocking and tracking prevention with selectable protection levels. Copilot can summarize pages, answer questions, compare options, and help with tasks using open-tab context. Other listed tools include AI-powered tab cleanup, theme creation from words, and a scareware blocker. Security features help block phishing and malware; Password Monitor can alert users if saved passwords appear in an online leak. Sleeping tabs pause inactive pages to reduce CPU and memory use. Energy Saver may provide an average of 25 more minutes of battery life, though results vary with settings and use. Mac features include Spotlight search, Touch ID, trackpad gestures, and macOS visuals. Edge also offers an in-game browser for PC gaming and access to free Microsoft 365 web apps. Feature availability and functionality may vary by device, market, and browser version.
