choosing a config to test

It is best to look at the existing pattern of data you see when looking at all the starred instances. Typically when adding a comment to a bug while triaging it is normal to list the configurations that the failures are most frequent on. Usually pick the most frequency configuration, maybe if it is a tie for 2 choose both of those.

If there is not a clear winner, then consider a few factors which could help:

• debug typically provides more data, but takes longer
• pgo is harder to backfill and builds take longer- try to avoid this
• ccov/jsdcov builds/tests are only run on mozilla-central- avoid these configs
• nightly is only run on mozilla-central- avoid these configs
• mac osx has a limited device pool- try to pick linux or windows
