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><div><br></div><div>- Jim<br></div></div></div>
