If you want to leave feedback for Firefox developers, you can go to the Firefox Help menu and select Submit Feedback... or use this link (submission is currently paused). Your feedback gets collected by a team of people who read it and gather data about the most common issues.
If you need to file a bug report or feature request for Firefox and other Mozilla products, see File a bug report or feature request for Mozilla products for details.
