Google always shows that message to you if you've never seen it before. The site judges whether you've seen it before by saving a cookie when you click off the message and watching for that cookie. If you clear google.com cookies, then the message comes back.

Over the years, users have turned to add-ons to hide these and other annoying "in-page" messages. Extensions to do that include

• Adblock Plus, Element Hiding Helper (I haven't tried it myself): https://addons.mozilla.org/firefox/addon/elemhidehelper/

• Remove it Permanently (I haven't tried it for this): https://addons.mozilla.org/firefox/addon/remove-it-permanently/
