921293 - Don't print NS_WARNINGs if an environment variable is set

Status: RESOLVED FIXED

(Core :: XPCOM, defect)

Attachment: silence-warnings

It's useful to be able to see JS errors on stdout when running debug builds. However, there's a lot of debug spew that gets in the way. Some of it can be disabled with MOZ_QUIET. However, there are still a lot of lines printed from NS_WARNINGs. Ideally we would fix these, but the same ones have been printing for quite a while and on every browser startup, so that seems unlikely. This patch adds another environment variable, MOZ_IGNORE_WARNINGS, that allows you to silence these messages. Possibly we should use MOZ_QUIET for this purpose as well?
