**Do not open issues because web pages are broken as a result of uMatrix blocking stuff because of your ruleset.** The issue is with your ruleset, not uMatrix.
**The issue tracker is for provable issues only:** You will have to make the case that the issue is really with uMatrix and not something else on your side. To make a case means to provide detailed steps so that anybody can reproduce the issue. Be sure to rule out that the issue is not caused by something specific on your side.
