Facebook profile pictures are no longer zooming

[mleyen]

Hovering on a profile picture anywhere on the site does not expand it. It shows the popup, but the image is only at 100x100.

This does not happen to all pictures, but still most of them.

When pressing T to open the expanded image in a new tab, the URL looks like this:
https://scontent-fra3-1.xx.fbcdn.net/v/t1.0-1/p100x100/12208495_10102454385528521_4749095086285673716_n.jpg?oh=507433f597ae1fe749c2086f064a0384&oe=5780B504

Individual pictures in albums are also not expanding at full. The popup URL is:
https://scontent-fra3-1.xx.fbcdn.net/v/t1.0-0/p206x206/12800183_10102686033653821_4456671336074950529_n.jpg?oh=ed6bca5fde37c6129068313f2866a564&oe=57767CDF
Compare with the real full-size URL:
https://scontent-fra3-1.xx.fbcdn.net/t31.0-8/12783754_10102686033653821_4456671336074950529_o.jpg

I am having the same problem on Facebook in the last couple of days. Hardly any pictures are expanding and the thumbnail icon only appears for a fraction of a second and then disappears. I've tried posting on the Thumbnail Zoom Plus Facebook page and just emailed David, but have not heard anything. Do you know of another good add-on to use while this one isn't working? I use Firefox 45.0.2 and have the latest version of TZP 3.8.

I am also having the same problem on Facebook! Only a few of the photos will zoom. Problem showed up in the last few weeks. Just get a tiny white box when I hover over the photo and then nothing. I have no issues on the other pages supported by TZP. I use Firefox 46.0.1 and have the latest version of TZP 3.8. Note that I have no issues with Twitter.
