User Agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:53.0) Gecko/20100101 Firefox/53.0
Build ID: 20170504105526

Steps to reproduce:

I've created a zip file of 5MB and sent it to my mail.
I've then tried to preview/open this message from my inbox.



Actual results:

Thunderbird takes 6 seconds to preview or open this message.


Expected results:

In previous version I've never seen such a slow behaviour.
It was as fast as if it didn't have any attachment.
I think it has been introduced in 52.
Attached there is the file used for the test
Sorry, my fault.
It simply was Look-Out plugin.
Disabling it solved the problem.
