Fonts Look bad on 1920x1080 monitor? How can I fix (anti-aliasing?)

My fonts looks really bad in FireFox and other application menus. I have set the "scale" to 1.5 in settings.. making it all bigger seemed to help the desktop... but all the apps still looks really hard to read. I have been googling for hours and I think it has something to do with antialiasing, but i can not work out how to fix it.

Any help will be awesome. I am using a fresh(ish) install. As in I have done nothing but install it, and install my fav terminal app. I am not a pro-Linux user, so if you have time, it would be helpful to have good instructions... of course any info is better than nothing.

Thanks!
