Here is an example of a screenshot I took and pasted into this forum

As you may or may not be able to see.

The image gets pasted twice.

I don't understand why. But it does this everytime.
I am using Firefox.
I suspect this happens to a lot of people, but nobody writes about it because they are already here about something else maybe ?
