SiteAdvisor now has an icon (the M shield) in the address bar of Chrome but it's not working properly. The icon in the page for chatelweb.com (a site whose owner is asking about delays in testing) is Grey, as might have been expected : but it's not immediately obvious whether it's Grey because the site is untested or for some other reason. Clicking on the icon produces a mini-balloon with no content, which is not helpful; and in the Chrome console there are two errors (repeated many times) which imply that something is not being found in the expected location.
In fact the Grey icon does imply Untested, because the icon for this page shows (as expected) Green. So the errors may relate to the lack of content in the balloon, which is likewise empty on this page.
Edit - Chrome version is the latest, Version 33.0.1750.149 m (updated earlier today)
SiteAdvisor version (in Chrome) still shows as 220.127.116.11
