I am really getting tired of TBird resetting my all my default preferences whenever there is an update. One more time and, contributor or not, I'll abandon the app. I've lost critical emails in the past. This time it's reverted my Threads setting and there seems to be no way to get rid of these damned thread filings. I don't want threads. They make no sense for me and my correspondences get lost as they are buried deeper and deeper into the ooze of Thread world. Can somebody tell me how to turn these things off? And can somebody please, please, please tell Mozilla to stop screwing with my settings when they update!? And don't tell me they don't because we all know that they do.
