User reviews
Microsoft Defender Browser Protection is praised for enhancing security, blocking malicious sites, and ease of use. It works well with Windows Defender and effectively blocks pop-ups. However, users report false positives affecting safe websites, occasional flickering during warnings, and difficulty disabling the extension, especially on managed devices. Many users are unhappy with the extension promoting Microsoft Edge and ending support for Chrome. Notifications and alerts are minimal compared to paid antivirus products, which impacts user experience.

- Extension sometimes causes websites or tabs to flicker or briefly blackout, leading to confusion.
- Cannot be disabled or removed easily, especially when installed by policy on work devices.
- Promotes Microsoft Edge by pushing users to switch from Chrome, upsetting some users.
- Limited notifications and lack of detailed alerts compared to paid antivirus software.
