I can't remember if this matter has been raised before, but I can't find anything relating to it, so here goes.
When you create a folder in Moz (to filter your mail) there seems to be no way of emptying just that folder, and you have to delete messages one by one. I receive about 200 mails a day and I have been testing Mozilla News (with and without Enigmail) with this high level of traffic. Most of the other bugs I have come across are minor compared to this omission. Is there any chance this could be incororated into the next build? -- Graham
