Steps to reproduce:

Try searching by image on a web app like Bing or Yandex. You should see that sometimes when you drag and drop an image, Firefox opens the image instead to trigger a drag and drop on the web page UI. And when that happens, you can't just go back, you have to reopen the app.

Up to know, I've never figured out why this is happening, I guess it's a bit weird.

Since nowadays, HTML and browsers are used to create UI, it is a great feature to have interference between the business logic of the browser UI and the webpage.

I can understand Firefox reacts to an HTML document drag-and-drop on its window, but why do that for an image. Firefox is not an image viewer.
