Set facebook content to 100% width after removing column between content and chat

This was an error - the script had become disabled in the Greasmonkey settings. However, since then it is stopped working properly when enabled. See next post.
Stopped working mid-March 2017
This script used to work perfectly, but now does nothing. FB page is unmodified, displays the same with script enabled or disabled. I hope it can be updated to work again.
