I am running Snow Leopard 10.6.5 with Google Chrome dev version 10.0.612.3. To access your plugins within Chrome, type "aboutlugins" into the omnibox. Then to the right, click on the "+ Detail". Scroll down to see your Quicktime Plugin version. The reason I am asking is as you can see, Chrome says I have an outdated Quicktime Plugin. I followed their link to Apple's Quicktime download page but Apple only offers Quicktime for 10.5 - 10.5.8 ,version 7.6.9 for Leopard. (http://www.apple.com/quicktime/download/) Anyone able to clear this up? It says I have to "download a critical security update" for my Quicktime Plugin as you can see from the attachment. The reason this has come to by attention is because the Facebook chat sound notification does NOT work while using Chrome. I did some googling and found that Quicktime may be the problem for the Facebook chat sound notification to not work. So if I do indeed have the latest Quicktime player (7.6.6), then why isn't the sound notification for Facebook not working? Maybe because of something else?
