Yep was wondering if this is a Netrunner issue?
As never had firefox font issue of sites text too small.
Usually these sites fonts are about 2x the size they are now.
Being older with reading glasses smaller means more difficult to read.
Still readable just more effort and sitting closer.
As have Firefox checked for letting sites choose their own fonts.
But this is the only distro that have too small fonts for many sites.
System Settings to change?
As don’t want to have turn off let sites choose their own as can make a mess of some sites.
