Opera browser goes free

In the latest version of the popular Opera Web Browser, the banner ads embedded in the browser application window have been removed. The browser is now officially completely free. Previously, you had to pay for the ad-free version. I test drove the new version, and while it seems to feature-filled and loads super fast, I miss some of my favorite featurs from the Firefox browser. Unfortunately, the Opera browser has no room for user modifications and plug-ins the way Firefox does.
