On our website we have a slider with about 10 images that have always worked. Now, users who installed the Firefox update to 35.01 can't see the full images. Instead, some images are cut off 20%-80% of the way down on the slider, whereas others are untouched and completely visible. Size/type of image has no bearing. Has anyone else experienced this?

Thanks for the response. I checked and didn't see any errors, but I'll be using this plenty for future issues so I appreciate it!
