I am having issues with the readability of the menu in Firefox.
Some months ago you fixed the issue, in this post:
@bonbonthief, the fix I implemented was adding -webkit-text-stroke: .35px; /* Hack to fix thin text in Windows */ in style.css, on any elements where the font-family was set to Quicksand, since that seems to be the problematic font. This appears to fix it for me in webkit-based Windows browsers, but YMMV.
However, Firefox still has the same issue.
Or can I change some code anywhere myself?
