The fox’s appearance on the original logo has been changed through out the years by adding details to its face and tail and the globe kept getting lighter but that stopped with the latest one. The new Firefox logo has familiar elements of past like the fox and globe but is illustrated with bold colors and simplified shapes. Also the new tail is much more flame-like, creating a more elemental version of the fox. The Firefox logo still stands to this day and seems to have passed the test of time.
