There’s an interesting Google experiment that seems to be limited to Chrome 27 (dev/canary channel). The experiment removes Google’s navigation bar from both the homepage and the search results pages.
To confirm that the experiment is limited to Chrome 27, I opened Firefox, changed the user agent to “Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.33 (KHTML, like Gecko) Chrome/27.0.1441.2 Safari/537.33” using this extension and the navigation bar was gone.
Maybe the experiment has something to do with all the strange features that will be added to Chrome: search box on the new tab page, special Google interface that removes the search box, replacing the URL with the search terms in the address bar for search results pages. More about this in a future post.
