I've had reports from customers that try to checkout with Firefox that the credit card fields are unusable. The form fields turn into animations, almost like an animated GIF and will not stop. It is difficult to describe what is going on. Here's what it looks like:https://i.imgur.com/mTJfDeD.mp4. I don't know how else to illustrate the issue. I've had reports of this for several months, but can't seem to find the issue. Has anyone else run into this?
