Gray boxes appearing at the end of Tumblr posts.
I recently switched from using Safari to using Firefox as my primary web browser and I've noticed that now every time I post a grey box appears at the end of the post when you view it on the dashboard and I can't get rid of it. They look like the boxes that sometimes appear when you try to post pictures or gifs, but it happens even when I'm not posting those things. When you click the box it takes you to that post on my blog. Every time I edit a post another box is added on. It happens on original posts and reblogs. I asked Tumblr support about it and they said it probably had to do with my add ons or plug ins. But I tried disabling each individually and it didn't help. Anyone know what I can do to fix this?

Ok so I've figured out I can get rid of the boxes after they've appeared by editing the HTML on the post. Within the problematic HTML it says 'Java' so that must be causing the problem. But I already updated Java so I don't know why this is still happening.
