Middle-aged bugs

This is a project to work on Firefox bugs reported in a range time of -6months(-180d) to -1months(-30d).

These are bugs that haven't been changed recently, but were reported within the last 6 months. Triaging them may find good, relevant bugs. It can also help clear out invalid bugs!

      • eg. can you still reproduce the bug?
      • eg. could you provide more info about this?
    • ask for whatever additional details you need to understand
  • Replicate the bug
    • if the bug is an enhancement request set the severity flag as enhancement
    • if you cannot reproduce the bug
      • if the reporter doesn't answer 1 week later a requested need-info flag and the bug is INCOMPLETE tag the bug as closeme yyyyMMdd (perhaps 2 weeks later?) and wait for that period before you close it.
      • if the bug has all the info you need to close it, close as WORKSFORME or INVALID
    • if you cannot reproduce the bug and you are on a different OS add a need-replication tag

Remarks

  • If a bug reporter hasn't answered to qa requested added in the first week after he/she reported the bug, they are more likely to be not interested anymore.
  • Some of these bugs have more than one comment, maybe those are more likely to be significant and already started to be triaged.
