Opera 9 is one of the longest-surviving web-browsers out there, eclipsing classical Netscape and dodging any purchase and eliminate moves from Redmond. Some common features even appeared in Opera first. Back in the late-1990’s, I remember seeing “tabs” in use (but they were along the bottom of the window then!).
Over the years the makers of Opera (also called Opera) have been very supportive of the GNU/Linux community.
Several versions of their browser have been available for us freedom lovers, especially for users on Apple’s PowerPC chips and even a .deb package for Debian on Sparc. In recent years Opera’s blistering speed and compact size have given it a comfortable home on hand-held PDAs and mobile/cellular phones, so much so that they have been able to drop the price to a beautiful zero Norwegian dollars (for non-Americans out there, the currency is actually called “Kroner”).
Now all that power and excitment joins forces with the power and ease-of-use of Ubuntu. Opera 9 is now available with Ubuntu 6.06 LTS upwards—installing only takes a couple of clicks (directions behind the link). KDE and Kubuntu fans can also rejoice because Opera uses the Qt libraries and will fit in perfectly with your desktop.
