BrowserVet - Extension Permission Risk Auditor

About

Are your Chrome extensions spying on you?

  Most people install extensions without thinking twice — but many of them silently request permissions to read your browsing history, access your passwords, inject scripts into
  every website you visit, and even control other extensions.

  BrowserVet is your personal browser security guard. It scans every installed extension, analyzes its permissions, and gives you a clear trust score so you know exactly which
  extensions are safe — and which ones are a threat.

  What BrowserVet Does:

  - Assigns a Trust Score (0-100) to every installed extension based on 6 weighted security factors
  - Classifies extensions into risk tiers: Low, Medium, High, and Critical
  - Detects permission changes — get alerted instantly when an extension quietly adds new permissions after an update
  - Lets you disable or remove risky extensions with one click — no need to dig through chrome://extensions
  - Runs automated background scans every 6 hours so you're always protected
  - Exports detailed PDF security audit reports with full trust score breakdowns

  Trust Score Factors:

  Each extension is scored across 6 dimensions:
  - Permission Scope (30%) — How sensitive are the requested permissions?
  - Publisher Trust (20%) — Is the developer verified and reputable?
  - Update Recency (15%) — Is the extension actively maintained?
  - User Base (10%) — How many users trust this extension?
  - Review Sentiment (10%) — What do other users say?
  - Permission Justification (15%) — Do the permissions make sense for what this extension claims to do?

  Why You Need BrowserVet:

  - 1 in 3 Chrome extensions request permissions they don't need
  - Extensions can silently add new permissions during updates
  - A single malicious extension can steal passwords, read emails, and track every site you visit
  - Chrome doesn't warn you when extension permissions change after installation
