Just upgraded to TB v68.3.1. Now every single theme is not compatible. And, I cannot find any that are in the 'add-on' store. I really don't like this UI. UI

Why did you disable every single theme and force us to use something we don't like? Why would developers want to create new add-ons of any kind when you do this? At least give us something besides dark mode or light mode.

That sucks. I wonder why TB developers would do this.

Because they had to. Thunderbird is built on a "mozilla engine" the same one Firefox uses, Mozilla Co got rid of themes. Therefore Thunderbird basically has to as well. Fighting the change would have consumed more developer hours than were available. What happens in that regard in the future (years out) is hopefully something else will replace it. But at this time, we have what Mozilla left us (web extensions and some parts of the legacy extension which have been removed since Thunderbird 68 was released.) The developer team are concentrating on making Mozilla web extensions fit for mail use. (they might be adequate for browsers, but they just don't cut it for add-ons in a mail program as they by design limit access to the local program and file system. Great for security in a browser were an extension might occasionally want to save a file. Bad for a mail system that lives on the local hard disk. So it was a matter of priorities really. Pretty over functional. Functional won out

Themes are no more, I am sorry you do not like that, but it is how it is.

Thank you Matt for the explanation. It makes perfect sense now why Mozilla did this. Do you know where I might get an older version, like v60 something IE: 60.9.1?

Thank you again for your excellent analysis, and your patience with frustrated me!
