GoogleGuy responds in this thread discussing the fact that the Google Toolbar automatically updates to newer versions without giving the user an option or notification of the upgrade.

Hey amznVibe, the fact that the toolbar auto-updates is listed in the first 10 questions of the Frequently Asked Questions (FAQ) pages:
There are lots of good reasons to auto-update the toolbar. For example, about two years ago, a security company found a potential security issue with the toolbar. The toolbar team went into a non-stop quest to find and fix any security issues. With auto-update, we were able to deploy the fix to toolbar users before anyone but the security company knew about it in the first place. So we want users to be informed that the toolbar auto-updates, but I think that in general it can be a very useful feature to auto-update.
bateman_ap, I think that the toolbar team took care not to enable any extra options (e.g. pop-up blocking) if the toolbar upgrades--let me know if you find otherwise, and I'll pass the feedback on. The upgrade does have a lot of useful features that I think people would like (it took me about 10 minutes to really want the new version instead of the old version), and I'm not aware of any features that went away, so I hope people will explore the new version for a little while before assuming that the upgrade is for the worse somehow.
