Why SNap and not Flatpak for the Beta?
I guess there may not be an at all satisfying answer to this question, but I want to use and help test the Thunderbird beta, and somehting has me confused. Why would the Beta have an official Snap but not a Flatpak? That makes absolutely no sense to me.
Only Ubuntu and its related projects support Snap by default, and many of Ubuntu's derivatives - including Mint, which is more popular than Ubuntu itself - disable/remove Snap from the default install. Meanwhile, Flatpak is enabled by default in many other distros, including the aforementioned Mint, Fedora, and Manjaro.
So, why not support flatpak?

Glad to hear you want to use and help test Thunderbird beta. You will want to install beta in it's own directory, do not overlay the Thunderbird release version. Visit https://www.thunderbird.net/en-US/download/beta/ and note the instructions.
An official Flatpack for Thunderbird is still being worked on at https://bugzilla.mozilla.org/show_bug.cgi?id=1290670
Does this help?
