<p>Thanks for the rundown of numbers, Wayne!</p>
<p>I don't see any possibility to go 32-bit only. Given 64-bit is
only available since around 2 months (and beta only), it seems too
soon to make it default. It's something to consider, but I believe
it also needs some technical work for migrating existing users.<br>

<pre class="moz-quote-pre" wrap="">FYI, Wayne is working on getting us numbers, and will try to send them

(Based on his initial queries, it seems there are still a considerable

<p>Indeed, there is a sizable set 32-bit Windows users. The
following is likely a fair estimate of our WINDOWS user
population via crash statistics. The numbers are percentage of
users, and virtual memory size of the Thunderbird process. <br>
