First.. I HATE threaded messages. I'm sure there are plenty of use cases for it but I truly despise all things threaded when it comes to e-mail. Yet somehow mozilla seems to believe that it must be that absolute best thing in all the world for everyone to use. As there appears to be no way to GLOBALLY disable the use of threaded messages. By disable I mean, I don't even want to see a threaded column. I never want to see messages from any folder or new mail account even have an option for threaded. I want the entire feature to be completely removed. While I'm sure that removal of said feature is pretty much something that isn't going to happen. It would be nice to have a way to simply not have it be used at all. I shouldn't need to go and highlight a bunch of folders or turn it off EVERY time I add a new folder. I HATE sort by threaded because I HATE threaded messages. So why isn't there a way to just turn it off.

So.. I'm using a DESKTOP version not a mobile version. And NO I don't want to highlight folders.. there MUST be a way to just turn off threaded completely.
