One of the biggest complaints about IE9 Beta has been the location of the tabs in relation to the address bar. I haven’t had any issues with it, but Microsoft has responded by allowing users to move the tabs to below the address bar. Of course, this isn’t good enough for everyone, some of which would rather have it ABOVE the address bar.
Microsoft is currently testing builds of Internet Explorer 9 that include the ability to re-position the tabs to below the address bar. The current public beta build does not include this capability and Microsoft is expected to build this into the Release Candidate. Users can turn the functionality on by selecting “show tabs below address bar” after right clicking in the tab area of Internet Explorer 9 (see video below). The option will address some complaints from the public beta.
