Version 3.0.5768.6 Firefox 41.0.2
I've noticed in the last couple of versions that I am not able to select the different types of artwork when searching for new images in the image editor. I click on the drop down and nothing happens. If I have a lot of images to choose from and hit the arrow to go to the next set of images and then go back, I am able to click the menu. Doesn't seem to be an issue in Chrome. Wondering if there is some plugin that may not be active in Firefox that could cause this?
