How to edit or delete a posted Firefox Support question or reply?
Is there a way to make changes to a Firefox Support question that I've posted (like fixing typos, etc.)? And/or make changes to a reply I've posted to someone else's question thread?
And how do you entirely delete your posted question or reply, if you wish to for any reason?
To change your message, press the three dots at the upper-right of the post.
The question section you can edit via the Question Tools menu -> Edit his question. A reply you can edit via the three vertical dots menu next to this reply. You can't remove a reply, but you can clear its content and leave something like '(deleted)'.
