Fix Firefox Font Rendering Problem in Snow Leopard
August 30, 2009
Upgrading my iMac to Snow Leopard, one of the oddities I ran across was that in Firefox 3.52, a number of pages had their normal fonts replaced with “Courier” in odd places. Opening Font Book, I noticed that a number of fonts commonly used on web pages (Ariel, Verdana, etc.) showed that “duplicates” were present.
I right clicked on each of these, selected “Resolve Duplicates” and restarted Firefox, after which everything was back to normal.
No idea what the cause of this was, just thought I’d toss this out in case anyone else runs into it…



You are a SAINT! Thank you!
I’m having the same problem, but it didn’t work for me…
Thanks for that, weird action, eh? Still, all working now, so cheers!
I had the same problem when opening up Yahoo Mail. Some of the fonts were messed up. This was after my install of Snow Leopard on a MacBook Air. Thanks a lot!!!! You saved me likely hours of frustration. The net (people) is good.
i will try~
THANK YOU!!!!
I have had the same problem than Andersius, but finally I tried the same steps with Lynotype and then I resolved the problem!!
