Alright I'll repost the content of that post here
"So I don't really know why but in my build of Firefox no matter if I
tell it to use system libs or not it will downscale images poorly
https://a.desu.sh/evknqh.png on the left is firefox-bin and the right is
my build. I'm not sure what exactly is going on here but I need to
compile Firefox against gtk2 in order for my filepicker patches for glib
and gtk+2 to work with it. Compiling it against gtk3 results in the same
thing. Here is my emerge --info.
*Code:*
    emerge --info firefox
