Firefox extension audit – FoxyProxy permissions review, risk analysis, CSV log, screenshots, and security best practices.

Audit installed browser extensions, identify suspicious or unnecessary ones, and take appropriate action (disable/remove).

1. Checked installed extensions in Firefox (about:addons → Extensions tab).
2. Found only one extension: FoxyProxy.
3. Opened its Details page and reviewed:
   • Permissions
   • Private Windows access
   • Developer info & update history
4. Permissions Analysis:
   • Required: Download files, modify download history, control proxy settings, access browser tabs.
   • Optional: Clear history/cookies, modify privacy settings, access data for all websites.
   • Risk flags: Broad all-sites access (*://*/*), modifies privacy settings, high control over browser settings.
5. Decision:
   • Kept the extension (needed for proxy switching on Kali Linux).
   • Disabled unnecessary optional permissions and Private Windows access.
6. Verification:
   • Checked about:performance → No unusual CPU/memory usage.
   • Browsing behavior normal; no pop-ups or redirects.

Even with a single extension, the audit process ensures awareness of permissions and potential risks. Regular audits are recommended to maintain browser security.

• Install extensions only from official sources (AMO/Chrome Web Store).
• Review permissions before installing.
• Disable/remove unused extensions.
• Disable Private Windows/Incognito access unless required.
• Periodically review installed extensions.
