I thought the answer to the question would be obvious – not so as the people at Slate point out.
Predictably, Microsoft is not amused – and have said so: “‘Given the security issues with plugins in general and Google Chrome in particular, Google Chrome Frame running as a plugin has doubled the attack area for malware and malicious scripts. This is not a risk we would recommend our friends and families take.”” This sounds like the Politics of Fear response from Redmond. So Google has responded to the attacks by refuting the Microsoft claims as baseless because a)Chrome sandbox is better and b)only 1/4 IE browser users are at IE8 and many of the security features of IE7 and IE8 require Vista or Windows 7 and don’t work in Windows XP.
What makes this more compelling is the fact that on Windows, Chrome is the fastest browser according to Computerworld tests and Chrome Frame delivers this performance and standards compliance to IE. This may be enticing for shops which still have IE6 and IE7 [ 72% of all IE users] and want to improve security, speed , web standards compliance and go to a full feature set by just adding a plugin.
