Notice that you can use mid:$msgid$ instead of email:$msgid$.

    thunderbird 'mid:tqr8et$mrc$1@ciao.gmane.io'

opens the message in a new tab or a new window. Sometimes separate tab 
is inconvenient, but context menu has "show message in containing 
folder" item. ESR releases 91 and 102 support it out of the box. Whether 
thunderbird.desktop contains "x-scheme-handler/mid;" in the MimeType 
parameter (and so desktop-wide integration out of the box) depends on 
particular Linux distribution. For emacs it means that (browse-url 
"mid:tqr8et$mrc$1@ciao.gmane.io") should just work.

This approach can be used with "mid:" scheme for links in Org files as well.

There was a lag between thunderbird-78 and some later version when there 
was no easy access to Message-ID header in add-on API. Likely it is a 
reason why cb_thunderlink has a warning that such links might be broken 
in future. I have not checked if standard API or custom low level code 
is currently used in cb_thuderlink for lookup by Message-ID.

In orco standard messages.query() is used to search for Message-IDs 
extracted from links, e.g. 
https://list.orgmode.org/t7q766$m5k$1@ciao.gmane.io It is convenient to 
see message subject and date without leaving thunderbird. The main point 
of orco is opposite mapping. It makes possible to open in emacs the 
location in file that has link to current mail message.
