"Change the user interface icons"
How do I change the user iterface icons? You know, Back, forward, home, refresh? Preschool children draw better than this!

Please update to Firefox 67, 60 is out of date. I imagine you can change the icons using userChrome.css, but that's an unofficial hack that isn't supported.

I'd still be using 56 something, except I ran into unsigned extension issues with my plugins.
Everything worked fine until that. It was then I was forced to go to the ES version, that's supposedly current, only to have everyone tell me I have to update again. Have to.
Why do i need to hack the system and spend hours getting a usable browser?
There have been legacy system add-on published on the Add-ons website for older Firefox versions. See "For older versions of Firefox":
Those icons are likely SVG images for performance reason and not real images.
