Do you have any other icons on desktop, and is it just the firefox one? Could you post a screenshot just to give an idea.

And for some reason some icons don't show the right image, just a generic steam icon.. And the desktop icon of Rise of the Tomb Raider is not there...And the game is installed.

By the looks of it, you're using Mate desktop (or maybe is it Gnome 3?). On Mate you can resize icons individually.

Right click on icon > Resize icon = this lets you shrink or increase icon size
Right click on icon > Restore icon's original size = this brings the icon to normal size

I hope this helps :)

But why destroy it's majestic beauty?
It may be the only one of it's kind!
Is it really so bad that it looks a little different?
It is HUGE sure, but it can still have as useful and productive an existence as any other icon, can it not? Maybe one day all icons will evolve to these humongous proportions and maybe we should hope they do sooner than later--be it because of dimming eyesight with growing age or to make certain gnome design decision actually tolerable. ;-)

It was Gnome flashback with some MATE icons...

Now I installed Xfce 4 and everything looks fine...

Keep in mind that this upgrade from Ubuntu 14.04 LTS to Ubuntu 16.04 LTS was just an experiment I did in a backup system (the original SSD with Ubuntu 14 is safe) for to try ROTTR..

I am planning to make a fresh Xubuntu 18.04 install once I get a new SSD.. Now I need to tweak the system for to get rid of unneeded services and processes with Bootup Manager or something like that.

IIRC, in Gnome you can adjust the size of desktop icons by adjusting the settings for the desktop *folder* in Nautilus.

In any case, XFCE is a far saner environment; and it appears to have solved the problem.
