When a mozilla application crashed it'll ask you to leave a comment to try and help resolve the issue when it prompts to send crash info, and you used to be able to see all those comments on https://crash-stats.mozilla.org (it seems to be behind login or restricted access now). There was a lot of vitriol and unhelpful comments that any developer would need to wade through to get to anything to give them a lead

It also leave a coredump, they can remove repeated entries and then filter by good comments
