Last week I noticed something quietly frustrating about reading bugmail in Thunderbird… Someone had generated a bunch of bugspam while shuffling around bugs into new components, and I was cleaning it up. For the most part, sorting the messages by time and deleting a range took care of things. But, I realized, you can’t actually see who generated the bugmail from looking at the folder summary. So if someone else happened to make a change within the spam-timespan, I couldn’t easily tell. Sigh.
All bugmail comes with a From header set to “email@example.com” (which is basically useless), but there are also a number of other X-Bugzilla-* headers in each message. X-Bugzilla-Who, specifically, has the data I wanted to see. I just needed to have it exposed in Thunderbird!
I filed bug 557945, and the mail folks pointed out this could easily be done with an extension, and even provided links!
So, yadda yadda, a short time later I had written Thunzilla:
Thunzilla is available on AMO. Enjoy!
