Recently Added Photos for Google Photos от CrisValls

This Firefox Extension, adds a button to Google Photos to see the recently added photos in your gallery.
The button is located in the position marked in the image by a red rectangle, very easy to find!

Sadly, this useful option to see your last added photos (ordered by time) is not currently accessible on Google Photos website, so this extension helps you to have quick access to this option.

This is the direct link to access to you recently added photos: https://photos.google.com/search/_tra_

Enjoy it!
