 * Every issue should have **exactly** one bug/feature request described in it. Please do not file meta feedback list tickets as it is difficult to parse them and address their individual points.
 * Feature Requests are better when they’re open-ended instead of demanding a specific solution -ie  “I want an easier way to do X” instead of “add Y”
 * Issues are not the place to go off topic or debate.
-* While we do not yet have Community Participation Guidelines of our own, we ask that you show respect to everyone and treat others as you would like to be treated.
+* While we do not yet have Community Participation Guidelines of our own, we ask that you show respect to everyone and treat others as you would like to be treated. Behavior that would violate [Mozilla's Community Participation Guidelines](https://www.mozilla.org/en-US/about/governance/policies/participation/) is almost certainly unwelcome. However, as a small project without community managers, we cannot promise prompt and consistent enforcement.
 
 Please keep in mind that even though a feature you have in mind may seem like a small ask, as a small team, we have to prioritize our planned work and every new feature adds complexity and maintenance and may take up design, research, product, and engineering time. We appreciate everyone’s passion but we will not be able to incorporate every feature request or even fix every bug. That being said, just because we haven't replied, doesn't mean we don't care about the issue, please be patient with our response times as we're very busy.
