This is absolutely the second worst email software that I have ever encountered in my whole life. I am using it for the moment because the email software that came with my brand-new $5K mac is even worse. Let me tell you what went wrong just a few minutes ago. I edited a long email that I had sent to some recipients and that I now wanted to send to others. I was aware that my changes might not stick because thy already had not stuck in other experiences. So I make certain changes, and am aware that I have already made some of these earlier, like yesterday, and sent of the email only to find that the changes were gone. So, this time, I SAVED the edited email. That should protect my changes, thought I. I saved it, then I sent it, then I glanced at it, and one change I immediately noticed had been undone. Incredible, insufferable incompetence on the part of Thunderbird.
This might be a just a failure to retain changes, but I fear it might be something else--very aggressive correction on the part of Thunderbird, because its algorithm, written by some nitwit, tells it that for sure, I (the writer) made an error, and could not possibly have meant what I wrote, and so Thunderbird making the change for me, is doing me a favor. I could see such aggressive self-editing going on in the Mac Mail software. I have to struggle over and over again to make a change which Mac Mail keeps on judging to be illicit. It stupidly capitalizes when I don't want it, it stupidly inserts periods all over the place, which I have to go to the trouble to remove. In Apple's case, I figure they took everybody with brains and put them to working on cell phones, because that's where the money is, which left only morons to work on Apple computers. I can't imagine what Thunderbird's problem is. I swore years ago never to buy another Apple product again, because of idiocies that Apple was forcing on me, but relented and bought the current $5K+ machine because maybe Apple wasn't as bad as Microsoft, but not regret returning to Apple and swear again never to buy any Apple product again, this time really meaning it with my whole heart. And same with Thunderbird. I've got UBUNTU on a Dell laptop. I think I'll switch to it. Come to think of it, I might already have set up Thunderbird on it, and I don't remember anything like the current fiasco on that machine. Maybe the Thunderbird failure is only on Mac.
