Problems with Form filling when running Multizilla

I was having a very strange problem in Mozilla, starting around 1.4. I
could no longer double click on a form field and have it fill in my
data. I tried most everything I could think of, including upgrading to
various nightlies, and it wouldn't work.

Just today, I grabbed the latest 1.6a build. I had a problem installing,
so I started from scratch. Lo and behold, my form filling was back! So
I started adding my my extras and it stopped working. By a process of
elmination, I found it was Multizilla breaking it.

I can install the latest 1.6a, go to a page with a form on it, and it
fills in just fine when I double click. For instance, I've been using
a simple form for getting an email newsletter:

https://www.truthout.org/membership/sub_mgmt.php

I can just double click on the field and my email address gets added.

Then I install the very latest Multizilla, go to that page and double
clicking doesn't fill in my email address! Yikes! Any ideas? I need to
have both of these working. For right now, I've decided form filling is
better, but I need my Multizilla!

I'm running :

Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6a) Gecko/20031030 MultiZilla/1.5.0.3l
