# Legacy Firefox Playback Error Popup Guidance

This page is legacy Firefox/Test Designer troubleshooting content. Current Scenario Editor tests should use supported browser versions, Test Node logs, and execution output instead.

## Recommended guidance

- Do not use this as guidance for new Scenario Editor tests.
- Confirm whether the asset still depends on legacy Firefox or old Designer playback.
- Prefer supported browser and driver combinations for current AIQ releases.
- Flag obsolete Firefox-specific workarounds for removal or consolidation.

## Validation workflow

1. Reproduce the issue in a supported browser first.
2. Review AIQ output, Test Node logs, browser version, and driver version.
3. Use legacy notes only if maintaining an older asset.
4. Document the migration or retirement recommendation.
