I just discovered that Thunderbird 102.10.1 has changed pasting a link into a message, to format it as a "formatted" link, not the link itself. A search shows that ctrl/shift/v will paste the actual link. However, other programs paste the actual link, so remembering that Thunderbird is not standard is hard. I prefer the actual link text because that makes it obvious that it is a link and the viewer can see where the link goes. I suggest an option if some people want a formatted link.
