Extensions allow users to make their web browser their own by adding features and functionality directly into the browser itself, rather than as standalone Opera Widgets or Opera Unite applications. Developers can build extensions with the same web standards they already use to build websites and web applications. Better yet, with only a few tweaks to their code, developers who have already authored a similar extension for other browsers will be able to share their creation with more than 50 million Opera desktop users.
“Opera has always been customizable, but now you can personalize your browser in a new way through Opera extensions,” said Jon von Tetzchner, Co-founder, Opera. “We take pride in introducing new features to the browser. Now, other developers can join in the fun and share their innovations with millions of people. Everyone using Opera 11 will be able to personalize their browser in myriad ways, which opens up so many possibilities for making the Web a more personal experience.”
Make an extension in three steps:
1. Visit http://dev.opera.com/articles/view/introduction-to-opera-extensions/ for complete tutorials and a guide to getting started.
3. Upload to http://addons.labs.opera.com/.
Opera checks all extensions before they are made public to ensure the catalog of extensions is free from defects and malicious software.
