For me on Ubuntu (MATE) 20.04.6 LTS with Thunderbird
102.9.0+build1-0ubuntu0.20.04.1, this is the smallest patch I’ve found so
far to fix copy and paste from Emacs to a Thunderbird mail composition
window:

diff --git a/lisp/select.el b/lisp/select.el

Without this change I can paste a word into a Thunderbird input field like
To or Subject, but no into the mail composition area.

Pedro’s suggestion to use Ctrl+Shift+V (‘Paste Without Formatting’) instead
of Ctrl+V in Thunderbird works as well, without this patch.

I can’t reproduce the problem with deepl.com that Gregor described, neither
with Firefox 88.0.1 nor 111.0.1.
