Here is a screenshot of what I see. I am using Mozilla Firefox v.53.0.3 and have been using Firefox for many years.
I used to use a self made flag, combined Canada and Mexico into one flag as the avatar. It used to be in the spot where craig01B has a red beetle and where VeeDubTDI has the "TDIfest".
Since this started a day ago I have changed my avatar to a white Passat and it shows where it is supposed to be. But above the handles name is my original flag avatar and to the left of the day and time is my old flag avatar.
I have a photo attached.It is in the forum photo section.
I see I have to make the picture much bigger, for some reason it does not get bigger. Just found out if you double click the photo it will get you the larger version in the Photo Gallery.
