Update: 5/13/2016 10am I just uninstalled TZP and re-installed the latest 3.9beta1 and it's working great again. Yes! (Firefox 46.0.1, Windows 8.1)
Apparently just installing over a previous version does not work. Uninstall first then install.

I love Thumbnail Zoom but only if it works.
I just tried the latest update 3.9beta1 (the Facebook fix) and now on Facebook the little icon that usually appears when you hover over a photo doesn't even appear. It doesn't work at all.
I was running Firefox 47.0beta4. I installed 46.0.1 but still no Thumbnail Zoom.
(Windows 8.1)
Eagerly awaiting the fix!
I'm glad to see it's working for you after reinstalling.
