One of the features is Tab tweaks, which allows users to position the thumbnail images of their tabs either to the right or left-hand side of the browser, as well as at the top or the bottom, which was allowed in previous versions.
Opera has also extended the number of languages the browser is available in to 38 and implemented several changes to the user interface, which was created by Designer Jon Hicks.
However, the software company also revealed that it's recently launched Opera Unite software, which turns your PC into a web server, has not been included in the third beta as it remains in the alpha development stage.
"This third beta comes after a lot of careful improvements. We have never released such a solid piece of technology that not only runs seamlessly, but is so nice to look at as well. I am proud of this release, and I hope that the web-using world will benefit from a browser that is truly ready to do some heavy lifting," said Jon von Tetzchner, CEO, Opera Software.
Opera 10 can be downloaded from Opera's website.
