Not sure what you made to tricker Leak Monitor but try again with 2.0 or even in 1.5.0.7 RC5 http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/1.5.0.7-candidates/rc5/

Anyway, what we dont know is the bookmarks of Polonus 8) Certain type of sites are more likely to increase demand for tighter security than others. My feeling is if you can manage so much security stuff you either do visit risky sites or you dont really have actual need for them. Awareness or human factor is good enough protection. Not so much awareness among those Myspace users who recently got in trouble with their not updated most likely “cheap” XPs - still SP1 but they knew. Some dont care and just reformat or fix themself up with Anti-Spyware programs. People are different.

Matter of definition of course, if you count tracking cookies as a form of spyware/evil that must go away start protecting. And trust! I trust Opera, Firefox and IE7 to have high security as a goal. Dont think they can even compete on this issue any more. There will be single events showing a hole from time to time but I think it will be closed before it becomes a general problem. Goes for all 3 of them - though we might only hear most about Firefox “thanks” to open source policy. No bug is too small for Bugzilla which is good. When Microsoft give away a tool like Windows Defender they are aware and when Microsoft are aware rest have been since long. Not like you need 3rd party tools to avoid getting attacked. Can increase security for sure.

If it helps I remember a problem some had with Google toolbar or rather the phishing database. If you chose active protection during installation, each url send to Google, then it can get weird. Or at least some probably now fixed version could. Can also eat some cpu cycles. If you chose passive protection, only local database used, you should avoid most problems. Google toolbar itself should be pretty stable. Could be a Flock only problem, dont know…
