I'm having this issue with certain websites but have a specific one that clearly demonstrates it. presbyeco.com/presby-plastics and presbyplastics.com/presby-plastics are the same page in a Wordpress site. The first is the primary URL, the second is parked on it. FF has the problem on a number of sites with this situation even though the HTML delivered is identical. The DOM inspection reveals identical info also. I have also noticed that when going to the primary, sometimes the fonts appear huge initially then switch to the correct display. It is also interesting that it only happens to the Hn tagged text and not general text. Works correctly in IE versions (of course there are other issues!!!). Any suggestions/corrections? Thanks
