Questions to ask yourself
Can I reproduce it?
- Every time?
- Intermittently? If yes - how frequently?
- With a clean profile* (same channel/build)?
- With a clean profile* (different channels - most recent build)?
Being able to reproduce a bug only in certain channels (i.e.: in Nightly but not Aurora) is useful for knowing where the regression has occurred and allows developers to more easily uncover the root cause.
‘*’ Clean profile: when you launch FF with the profile manager, create a ‘throwaway’ profile to test the bug with so you know you’re starting with no addons, plugins, or other differences from a new installation of Firefox.
