Open the developer tools console.

//
I found similar defects, but they were so old, I could not believe that this could be the same one.  I don't know how to capture the version information you might need, so this is what I found in the "navigator" object.
navigator.userAgent
"Mozilla/5.0 (Windows NT 6.1; WOW64; rv:52.0) Gecko/20100101 Firefox/52.0"
navigator.buildID
"20170323105023"

It's current-patched Windows 7(amd64).
