In Chrome you can find out what is using CPU for each tab, there is a task manager.
Try the Firefox 3.6 beta I really really would hesitate to use IE at the moment, seeing as all versions including IE8 on Windows 7 are vulnerable to the latest China exploit - while it affects IE6 on XP most no versions are immune. Especially if you are known to have access to any valuable intellectual property! Chrome UI is an acquired taste, personally I find Firefox Chrome and Opera all comparable in speed, Chrome and Opera are the speed freaks in most tests. Safari is also very fast but tends to have more security issues than the others. >From what I have gathered, as details are deliberately a bit vague the "China attacks" worked like this: -They tried to hack into Gmail/Yahoo/Hotmaill accounts of known china activists and supporters. Gmail has now changed its default to https to make this harder - others are expected to follow. -Last year there were targeted emails sent to certain staff in the Dalai Lama's office, looking to be from someone the person knew with links to an innocuous web site, or attached photos/PDFs which had a malware dropper in it. Once loaded on the target PC, the Trojan started monitoring all email traffic and logins, and turned on web cams and microphones to monitor what was happening in the office around the PC, ie conversations nearby were also being monitored. Once security specialists were called in, they found also a significant number of Asian embassies of various countries also had similar spyware installed - it was described as the most sophisticated and comprehensive spyware ever seen The traffic looked to being sent to a site in China and Taiwan physically close to the Chinese governments electronic monitoring site, however no-one was sure of this as it could in theory have been going anywhere. -The Google and Adobe attacks this year look to be similar - There were targeted emails sent to staff deduced to have privileged access on networks eg to source repositories. The emails apparently looked innocuous and from parties known to the receiver (this is the targeted part - the senders had done careful research). Once installed the malware started downloading the source it could locate to web sites that Google identified as being Chinese. Google say up to 30 firms in California were targeted. The fact that they had publicly identified China as the offender implies they have done some thorough tracking of the destination of stolen data. This exploit is mainly in IE, and may also involve a PDF exploit as well. By all accounts Microsoft have conceded there is a problem in IE6 and do not yet have a fix, and it is not certain it can be fixed. Turning the security zone settings to High makes it less likely but is still not an absolute preventative. All versions of IE have this vulnerability. There was a similar serious problem with https in 2009 where a rogue web site could impersonate a legitimate site using a specially crafted digital certificate that had a binary null between the name of the impersonated site and the false site name - this allowed the certificate to be verified but the impersonated name would be shown, not the true impersonating domain. This meant that a man-in-the-middle attack for https traffic to in particular bank web sites became possible with no warning in the browser as the certificate looked to be verified (it was but for the malware domain). This vulnerability was fixed quite fast, but interestingly on Windows it affected IE, Chrome, Opera and Safari as they all used a Microsoft component to verify digital certificates - Firefox was the only browser immune in this case as it used its own component. Personally I prefer Firefox as its fast enough (close to if not fastest), best bookmarks search, and fastest consistently to fix security holes. However security is a constantly moving target and all software has its vulnerabilities.

I'm sorry but I disagree. If all of those tabs are loaded then it shouldn't be using any CPU, or a very small amount. Firefox has security issues, just like IE. I use both but prefer IE, it handles flash a lot better than Firefox. Couldn't get into Chrome. I installed Firefox on the mac but it just seems out of place so generally use Safari - even though it is a pain to use. I don't browse often on the mac.
