Opera is a compact, full-featured browser designed to be fast, with excellent accessibility options and an accurate rendering engine.
It also includes a newsreader and mail client.
It offers full control over cookies, encryption and other aspects of your personal data, and you have the option of clearing everything of a personal nature from the Opera installation. This can be done in seconds and ensures that there are no cookies, history traces or stored passwords on your machine.
All of this is offered additionally to the features for which Opera has now become well known, such as the ability to quickly zoom into and out of pages, the ability to navigate quickly and easily without using the mouse, the option to browse with graphics switched off, the simple way in which multiple pages are opened using tabs, the many search options and the rendering speed of the engine.
Add to this the wide range of options for customising the user interface, the ability of the browser to change skins, and the fact that it has a capable POP3/SMTP e-mail client and news reader built-in - and you'll get Opera 8.1.
It'll run well on a relatively slow machine, too, consuming very few system resources.
There are versions either available now or in development for Linux, Mac, OS/2, Solaris, FreeBSD, QNX and Symbian operating systems.
If you are tired of waiting for hours to open a new instance of your browser every time you need a new window, then Opera is the browser for you!
