Legacy Firefox HTTPS Localhost Troubleshooting for AIQ

Last reviewed: September 30, 2026

This page is retained as a legacy reference for older Firefox HTTPS localhost issues in AIQ environments.

What changed in this article

• Shortened the long question-style title and marked the Firefox/Designer localhost workflow as legacy.
• Replaced Designer wording with AIQ terminology while noting that old Firefox certificate/profile behavior may no longer match current browser versions.
• Added checks for trusted certificate, localhost URL, port 8443, browser version, proxy settings, and whether the issue still reproduces in supported browsers.

Validation workflow

1. Confirm the current supported browser path before troubleshooting an older Firefox localhost issue.
2. Verify certificate trust, URL/port, proxy settings, and whether the AIQ service is reachable on localhost.
3. If the issue is Firefox-specific, document the browser version and compare with a supported Chrome/Edge execution path.

Review note: This page should not be used as primary setup guidance for current AIQ browser testing.
