I run a 38.5ver portable app version of Thunderbird.
I've got it customized with a couple of addons, and use it occasionally on multiple computers in an IMAP configuration on all computers.
Works flawlessly.
Today, it seem like it 'updated' something, but when I looked to the changelog for updates, for 38.5 the updates were from 2015. 3 things, two of which was a security fix, and some sort of 256 something compatibility with microsoft.
I've got 'check for updates' turned off. So what happened today?
Why the informing of the update to 38.5 when the only updates seem to be from 2015?
I'm going to run a virus scan and see what is going on, but I'm asking just to double check that I'm not being overly paranoid.
I have configured Thunderbird Portable not to automatically update as per Mozilla's guidelines. Some users have noted that Firefox will now update anyway, so the same might apply.
Please note that neither PortableApps.com nor Mozilla support Thunderbird 38.x any longer.

Yes, I understand the security risks and act accordingly. Hence the paranoia and the question asking.
But it's interesting to know that you have experience with Mozilla ignoring user preferences.
It was a change pushed at some point that negated the "totally disable updates" feature that was documented by Mozilla in Firefox. I have Thunderbird and Firefox Portable set to check for updates but do not update automatically by default as required by our licensing agreement.
