Does Thunderbird work with Sonoma on a Mac?

I upgraded my Mac to the Sonoma operating system. Since doing so, Thunderbird won't open. Or actually, it pretends to open (the icon bounces up and down for a bit, then stops), but nothing works. The icon indicates it's open, but I can't access anything. If I right-click on it, and select "force quit" it looks like it's closed, but nothing else changes. I deleted my app, downloaded the latest version of Thunderbird, and it does the same thing. I read some things about the app storing documents separate from the app itself, but I couldn't find them on my computer. I have a lot of old emails that I need, as well as all my email addresses. So I have a few questions; does Thunderbird run on Sonoma (I saw a discussion board say something about Mac not supporting "legacy mail apps")? If so, how do I get it to work? If not, is there a way to retrieve my old emails or email addresses? Is running Thunderbird through a browser possible, and would that allow me to access my old documents?

I know a couple people for whom it works well. But there are also a few for whom it does not. So far :

Sorry that this reply is probably not particularly helpful for your specific problems but I can confirm that Thunderbird 115.3.1 is working perfectly for me under macOS 14.0 using an Apple Silicon Mac (in case that's relevant).

I returned to Thunderbird after 10 years away when 115 was made available so have not installed over any older version of Thunderbird.

Among the barrage of complaints about the look of 115 I have to say that, on the Mac at least, it's effective and perfectly usable (aside from odd problems with the Unified Folder view—which I don't bother to use as a result).

All I can say, constructively, is don't give up: it does work under Sonoma.
