Microsoft is rolling out a security update in November 2025 to block malicious sideloaded extensions in Edge.
What Are Sideloaded Extensions?
Sideloaded extensions are browser add-ons installed outside the official Microsoft Edge Add-ons store. Developers sometimes use this method for testing, but cybercriminals can exploit it to deliver malware, steal sensitive data, or monitor your online activity. Unlike official extensions, these bypass Microsoft’s security checks, making them riskier.
Why This Update Matters?
Microsoft’s update will detect and block dangerous extensions before they can harm users, helping protect privacy and security proactively. Imagine downloading a seemingly harmless extension from a third-party site. It installs quietly and starts collecting your online activity data and your passwords, all without you knowing. Scary isn’t it?
How You Can Stay Safe
1. Stick to official sources: Only install extensions from the Edge Add-ons store.
2. Review your extensions regularly: Remove any you don’t recognize or use.
3. Be cautious with external extensions: Avoid installing add-ons from untrusted sites, even if they seem helpful.
