When I choose the 'cleartype' font option under display in windows, the site looks fine again using firefox. But this time everything else in windows looks like utter tosh lol. So it's a perplexing conundrum right now. I'd rather keep the standard font option and browse the site with chrome.
One other thing i noticed is that coupled with the cleartype option, compared to chrome, firefox fonts look a tad more elongated , which is nicer.
