          <div>That's already there. Just pass --allow-downgrade when
            starting Thunderbird (or Firefox), and it'll perform the
            downgrade. I'm pretty sure once you do that, you'll be able
            to use the older version without passing the command-line
            flag (unless you upgrade again, of course). I think that's a
            pretty good compromise, since it keeps us from silently
            messing up people's profiles, but users still have a way out
            if they actually need to downgrade.</div>

    Just pass ---  Just explain that to the average user, that does not
    even comprehend there is a command line that arguments can be passed
    on, or that windows uses shortcuts.  Then repeat 500 times.  That is
    what I am expecting in the next release.  <br>
    <br>
    Simply put,  a support disaster with "add-on XXX does not work and I
    can't downgrade, how do I fix that bug?"<br>
