Browser Extension Security Risk Detection Guide for Edge, Chrome & Firefox

Nowadays, browser extensions have become powerful "helpers" in our daily work. Whether on Edge, Chrome, or Firefox, extensions can help improve work efficiency and enhance browsing experience. However, the convenience of extensions also comes with certain security risks. Next, we will provide a detailed guide on how to properly detect and protect against browser extension risks!

1. Common Security Risks of Browser Extensions

Before installing extensions, understanding potential risks is the first step to protecting yourself. Common security risks include:

1. Excessive Permission Requests
Some extensions request access to your browsing history, stored data, or even camera and microphone permissions during installation. Excessive permissions may be used to collect sensitive information.

2. Malicious Code Injection
Malicious extensions may inject scripts to alter web content, hijack input information, or even download harmful files.

3. Ads and Tracking
Some extensions earn profits by embedding ads or tracking scripts, which not only affects browsing experience but may also leak personal privacy.

4. Vulnerabilities from Outdated Updates
Extensions that are not updated in time may have known vulnerabilities that hackers can exploit.

2.Browser Extension Security Detection Methods

1. Official Store Security Check
Edge, Chrome, and Firefox official extension stores have security review mechanisms. Recommendations include:

• Download extensions only from official stores

• Check user reviews and ratings

• Pay attention to developer information and update frequency

2. Permission and Source Code Review

• Check if the requested permissions are reasonable

• If possible, review the source code to identify any suspicious code

3. Use Security Detection Tools
Besides manual review, using professional tools can more efficiently detect extension risks. For example, ToDetect Browser Fingerprint Detection Tool:

• Real-time Monitoring of Extension Behavior: Can detect if extensions secretly access user data in the background

  Chrome's "Safe Browsing", Edge's "SmartScreen", and Firefox's "Enhanced Tracking Protection" provide additional protection.
