What's to explain? (Perhaps the fact that you get this message when I
dont when I opened Tbird for the firts time.?)
Debian has packaged a "daily build" to give the "newest" Thunderbird, at
the time of packaging. When the package is updated you'll get a newer
version.
68.5.0 is the latest build of Thunderbird.

Re: [qubes-users] the qubes clipboard
Ulrich Windl: Hi! I'm very much confused with the Qubes OS clipboard: When trying to copy some text from a Temrinal, I mark the text with the mouse then press "Ctrl+Shift+C", and I get a confirmation that the text is copied. However when I try to paste the clipboard in another machine, the contents is not what I had marked. When I use the "Edit->Copy" menu in the Terminal after having marked the text, and then press "Ctrl+Shift+C" again, the correct text is put in the Qubes OS clipboard. Confusingly the Terminal displays the shortcut "Ctrl+Shift+C" for "Edit->Copy". Isn't that a highly confusing feature (slowing down productive work a lot IMHO)?
