Troubleshooting Referer Control for Chrome: Fixes for Common Issues

1. Extension won’t appear or install

Check Chrome version (needs recent stable release).
Reinstall from Chrome Web Store: remove extension -> restart Chrome -> install again.
Disable other privacy/security extensions temporarily (they can conflict).
Confirm extension is enabled in chrome://extensions and pinned to toolbar.

2. Rules not applied to sites

Ensure rule scope matches the exact domain (use wildcard patterns like ://.example.com/).

Verify rule order: some extensions apply the first matching rule—place specific rules before broad ones.

Confirm you’re editing the correct rule type (global vs per-site).

Reload the page and clear cache (Ctrl+Shift+R) after changing rules.

3. Referrer still being sent

Check Chrome’s built-in referrer policy: some pages set a strict-referrer header that overrides extension changes.

Ensure extension has necessary permissions (access to site data).

Test in Incognito with only Referer Control enabled (allow in incognito via chrome://extensions).

Verify other extensions or site scripts aren’t re-setting headers.

4. Extension breaks site functionality or login flows

Temporarily set referrer to send origin-only or full URL for affected domains.

Create a site-specific allow rule rather than a global policy.

Use browser devtools (Network tab) to compare requests with and without the extension to identify what the site expects.

5. Rules syntax or pattern errors

Use correct pattern syntax: scheme://host/path with wildcards (e.g., ://.example.com/).
Avoid accidental spaces or stray characters.
Test patterns on a simple known site first (example.com) to validate behavior.

6. Extension settings not saving

Ensure Chrome sync settings allow extension data to be stored.
Check for profile corruption: try creating a new Chrome profile and configure the extension there.
Update Chrome and the extension to the latest versions.

7. Incognito or profile-specific behavior

Enable the extension for Incognito explicitly in chrome://extensions.
If using multiple profiles, rules are profile-specific—replicate rules across profiles as needed.

8. Conflicts with corporate or managed policies

Managed Chrome installs (enterprise) may enforce policies that block extension changes.
Check chrome://policy for applied policies. Contact your IT admin if policies prevent modifications.

9. Debugging steps (systematic)

Disable all other extensions.
Reproduce the issue on a simple site.
Open DevTools → Network → inspect Referer header on failing requests.
Toggle rule settings (global → site-specific → allow) and observe changes.
Test in a fresh profile or guest mode.

10. When to seek more help

Collect: Chrome version, extension version, exact rule patterns, example URLs, and a HAR or screenshots of network headers.
Contact the extension developer (link on Chrome Web Store) or file an issue with collected details.

If you want, I can:

Check your specific rule patterns and suggest fixes (paste them here), or
Walk through a debugging session using a sample URL.
