Fixed jekyll default theme font-weight bug by changing from font-weight from 300 to 400 in _sass/_base.scss, still might be a Firefox bug as per this comment on jekyll issue 4042
Still might be a Firefox bug as per my previous blog post Possible font-weight bug in Windows and Linux?!?. If I can write a test case that doesn’t have jekyll in it, then it probably is a bug in Firefox.
