Remove Suspicious Browser Extensions Safely
A practical process for auditing and removing risky browser add-ons that may steal data or degrade performance.
Inventory installed extensions
You cannot secure what you do not track.
Create a quick list of installed extensions by browser and user profile.
Action checklist
- Export or capture extension list.
- Mark owner and business need for each extension.
- Flag unknown or unused extensions.
Evaluate risk and permissions
Broad permissions can expose browsing data and credentials.
Review requested scopes such as read/change on all websites.
Action checklist
- Check permission scope for each extension.
- Review publisher trust and update frequency.
- Search for known security incidents.
Remove and monitor
Remove high-risk extensions first, then monitor browser behavior.
Watch for homepage/search resets that signal remaining issues.

- Uninstall suspicious extensions.
- Restart browser and validate settings.
- Confirm no unknown add-ons reappear.
