how do i send an image. I've looked at the firefox programme files and the visual elents file show only the original (prior to today's update). I've tried to copy & paste the logo form the desktop display but nothing happens.

i've managed to get a screenshot but i cannot see where to upload it

Have tried to load screenshot to "add images" but the image shows as a black square. Not sure what i an doing wrong but have tried several times with the same outcome.
