Opera 11 also comes with another major feature called tab stacking that will come in handy to those who have large numbers of tabs open on a regular basis. So far there are a little over 130 extensions in Opera's extension gallery - a small number compared to Firefox or even Chrome, but the feature has been available only in a limited alpha release for the past month. The latest pre-release version of the browser uses a similar approach to that employed by other WebKit-powered browsers like Chrome and Safari, installing extensions as buttons to the right of the search bar that can auto-update. The first beta version of Opera 11 is out today, and as expected, it brings a very important yet long-overdue new feature to the mix: extensions support.
