I need to ask Mozilla to fix a bug in my/their account page. I can't add my secondary email because my emails all use the same name even though they are at different sites. How do I get developers to fix this simple authentication problem since we can't talk to any tech support?
You should create a bug report. https://bugzilla.mozilla.org/ https://developer.mozilla.org/docs/Mozilla/QA/Bug_writing_guidelines
