Opera Link™ is a free service that enables data sharing between all your computers and devices. It can synchronize your bookmarks, Speed Dial, notes and other useful browser information, so they are available to you wherever you go.
Opera Unite is an extensible framework that allows for several web services (referred to as "Applications") to be hosted from the user's computer, including a web server for hosting a site, file and photo sharing, a chat room, and streaming media. Opera Software has released an API to create new or improved applications for the Opera Unite Platform, and many have already done so. An Opera Unite user's applications run on a domain associated with their My Opera Community account, and are accessible from any web browser. For these applications to be accessed, the computer and the Opera Browser hosting the applications must both be running.
The included API uses HTML, CSS, client-side ECMAScript and a new server-side JavaScript technology with local file access and persistent storage. Unite Applications are packaged according to the W3C Widgets 1.0 specification. Opera also provides a vetted facility for developers to upload these user-created applications.
ScribeFire is an extension for the Browser that integrates with your browser to let you easily post to your blog: you can drag and drop formatted text from pages you are browsing, take notes, and post to your blog. Available for Chrome, Opera, Safari, and Firefox.
Video Blocker allows you to hide videos from channels that you don't like. You can specify these channels by right-clicking on a link to a video on YouTube or by adding them manually via the options page. You can also hide videos from multiple channels at once, by using a wildcard. Blocking videos with certain keywords in their title is also possible!
Good luck and happy video blocking!
