Widgets Icon - Do you see what I see?

Hi, All my Widgets (Top right corner) are showing as a tiny triangle, a half circle (it’s somehow very Egyptian) and a rather fetching lined half square which to me looks like a shelf bracket, All of these Icons are in blue.

Also when I hover over them the tiny triangle and Half circle turn black and the lovely little bracket line magically disappears.

It’s not effecting me that much but I’m thinking of trade marking it as a symbol of doom and putting it on some products, as I’m getting absolutely no sales on Amazon at the moment!
(just shows how much time I have on my hands at the moment )

Anyway to be serious is it just me or is this what everyone sees on their main seller page now?

I’m using Windows, its Firefox and it’s been around for about a month or so, so just wondering?
