Status: UNCONFIRMED

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:54.0) Gecko/20100101 Firefox/54.0
Build ID: 20170608105825

Steps to reproduce:

Printing content of this page: 
https://gameknot.com/annotation.pl?gm=216&pg=2

This is page 3 of a 3-page article, the other 2 pages printed to PDF without problem.

There are two places on page 3 where comments can be shown (presumably via JavaScript).
When I show the first set of comments (there are just 2 comments there) I can print the page to PDF successfully
But when I also show the second set of comments (there are quite a lot more comments, 26 total) the system hangs and I have to Force-Quit Firefox 54 (OS X).  This has happened 3x in a row.


Actual results:

System hangs (due to quantity of JavaScipt content??)


Expected results:

Page should have been saved to PDF (as I did with the other 2 pages in the same article on the same machine using the same sequence of steps).
