DO NOT donate to Thunderbird. Let it "die". As with all of Mozilla's software, that would be the best outcome - if it does, someone who isn't totally incompetent might fork it and actually improve it.

Literally every change that's been made to thunderbird in the last 10+ years has made it worse. Mozilla are doggedly using the same philosophy as they are with firefox: "in what new and exciting ways can we make it more shit?".

There are a bunch of things that I used to do in thunderbird with no problem on much less powerful machines that I can't do today.

For example, since they decided to rewrite their perfectly-functional calendar parsing in a trash language, it now eats 100% of my CPU for ~30mins at a time trying to parse my decades-long, many-many-thousands-of-entries calendar. Then when it finishes it notices that it's been 30 mins since it synchronised my calendar, so it syncs and starts parsing all over again! This effectively locks up the whole of thunderbird, making it totally unusable. This issue has persisted for years. The solution I came up with is "stop using thunderbird for my calendar".

There's a similar fun bug which means it won't sync my contacts anymore either. A feature that I had by about 2010 which my nokia phone could manage, modern thunderbird cannot do.

If you'd like another 20 examples of how it's worse today than it was 10 years ago, just ask, and I'll write up a hundred thousand words or so of vitriol.

It's extremely likely that next time I upgrade my distro I'll be shopping for a new email client. Currently I have thunderbird marked as held so that it doesn't upgrade. When I upgrade my distro there will be a new version of thunderbird, and I'd estimate about a 90% chance that that's when I'll make my exit, after ~20 years or so.

It's sad. Thunderbird used to be a great piece of software.

Don't give mozilla your money.

In all seriousness, it might be good to write up more of the issues that you have for at least a few reasons:

1. TB probably(?) doesn't consider use cases like the one that you described. If there is any hope of them fixing it, it would be best to be underscored in detail. Perhaps then someone can try to propagate some fake test data to try and test against.

2. There's always the chance someone might be willing to fork it in hopes of improvement (E.g. BetterBird; betterbird.eu)

3. Sometimes screaming loud enough gains attention of people in a position to do something about it. Not super common, but does happen from time-to-time.

4. Who would pass up a chance to embarass Mozilla publicly? :^)

		Maybe. I did try (politely, btw!) reporting a couple of issues on their bugtracker a long time ago, but the usual thing happened: nothing at all. IIRC there was no response of any kind. Which makes me reticent to put more time into writing more bug reports for them to ignore. I just found out about betterbird today. It looks interesting. I might give it a try. And if I see the same issues there, maybe I'll report it on their bugtracker. I and a bunch of others have been screaming loudly at mozilla for like 15 years now. They're not interested in hearing what we have to say. Which is why the firefox marketshare is as dismal as it is these days. As for embarrassing Mozilla publicly, apparently their troll factory watches HN - I got downvoted a lot for describing facts. I think the best option for me really is to just find a new mail client and be done with Mozilla forever. I said it before, but I'll just say it again: It's a real pity, Thunderbird used to be a truly excellent piece of software once upon a time. I remember switching to it from outlook and being all "Whoa! This is great!". It was a similar experience to going from IE6 -> Firefox. How the mighty have fallen.
