Wappalyzer for Firefox: Identify Website Technologies in One Click

How to Install and Use Wappalyzer on Firefox (Step-by-Step)

1. Install the Wappalyzer extension

1. Open Firefox.
2. Go to Firefox Add-ons (about:addons) or visit the Firefox Add-ons site.
3. Search for “Wappalyzer” and click the Wappalyzer extension.
4. Click “Add to Firefox” then confirm any permission prompts.

2. Pin and access the extension

1. Click the Extensions (puzzle piece) icon in the toolbar.
2. Click the pin icon next to Wappalyzer to keep it visible in the toolbar.
3. Click the Wappalyzer icon to open its popup.

3. Identify technologies on a page

1. Navigate to any website.
2. Click the Wappalyzer icon — it will list detected technologies grouped by category (e.g., CMS, analytics, web server, JavaScript frameworks).
3. Click any listed technology for more details or to open its website.

4. Use additional features

• View counts and version info (when available) directly in the popup.
• Right-click a page and choose Wappalyzer (if available) to run detection from the context menu.
• Use the extension settings (open from the popup or about:addons) to toggle detection options or reporting preferences.

5. Troubleshooting tips

• If detection fails, reload the page or open it in a new tab.
• Disable other privacy extensions temporarily (like strict content blockers) that may block detection scripts.
• Ensure the extension is enabled in about:addons and updated to the latest version.
• Restart Firefox if the extension is unresponsive.

6. Privacy and permissions

• Wappalyzer needs permission to access page content to detect technologies; review permissions on the extension page before installing.
