I would like to send a comment/ask a question to Mozilla to read. Is this the best way, or is there a direct email or online form (search sent me here)?
The title says it all. I won't bother with the issue until I hear this is the way to make contact.
Hi, 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. Your feedback gets collected by a team of people who read it and gather data about the most common issues.
On the other hand, if you want a reply to a support question, you could post the question here.
