If it’s a moral obligation, can I mention a problem on a forum without being asked for my bug report or my patch?

Or am I both morally obligated to use the software and either open tickets for any issue I mention or fix those problems myself?

You're not morally obligated to open bug reports, just encouraged. That's the way things get fixed with Firefox, and if you want that, then learning how to do it is a big help.

If you don't want to, feel free to ignore that recommendation.
