Audit Browser Extensions for Privacy and Security
Every extension can become an unnecessary permission or maintenance risk.
The aim is to help you complete one clear task, recognize what needs verification, and avoid the most common mistakes. Work through the checks in order, then use the real-world example to apply them to your situation.
This guide is designed as a practical decision checklist. Use the relevant official guidance alongside the steps, especially when rules depend on your country, device or individual circumstances.
1. List what is installed
Open your browser’s extension-management screen and write down which tools you actively use. Identify extensions you do not recognize, duplicate functions and add-ons installed for a task you finished months ago.
2. Examine requested access
Read what sites and data an extension may access. Permissions to read or change all pages deserve greater scrutiny than access limited to a specific feature. Check the developer, official website and whether maintenance updates still arrive.
3. Remove and restrict
Uninstall add-ons you no longer need. Where the browser supports per-site or on-click access, narrow permissions. Use built-in browser features for simple tasks when that reduces the number of external extensions.
4. Watch for changes
After an update, review requests for new permissions. Keep a shortlist of necessary extensions and test websites after removals. If accounts show unusual activity, change passwords using a trusted device and review browser sync settings.
