Could you share a screenshot?

I would love to. How do I upload an image here?

Below the textfield you will find a option to select and upload an image.

There is only post reply and cancel. There is no option to upload any file.

Are you trying to add it your original post or to new reply?

Fortunately I opened this email on my PC. Before I was using the mobile app. The mobile app doesn't appear to have the option to upload images. Here is the image I took from the mobile app.

I have never seen this kind of white icon. Looks like a orphaned app.

1. Delete the white app icon
2. Shutdown the iPhone
3. Start the iPhone again
4. Try re-downloading Firefox for iOS from the App Store.

Does the orange Firefox Icon show up?
