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!
