When I use the gmail link newly provided from the "new" google tool bar along the top of my browser window -- the gmail log-in screen is different from the log-in screen as it normally present's itself. This change occurred after this new set of links started appearing above the browser window -- this set of links appears only on the google home page. I did not install or accept the installation of any new tools or link add-on's for my Firefox browser. After this a hostile user has started logging in to political sites I frequent and is falsely using my name & identity -- as accessed through my gmail account. I have changed the passwords on my accounts but I still get the phoney looking gmail log-in from the new selection of links which recently began appearing a few weeks ago. When I access gmail from a google search I do not get this same log-in screen -- it is the older more familiar screen. Is my browser or system compromised?
