URL Filter API for Opera extensions

The URL Filter API for Opera extensions defines a DOM interface that allows extensions to add temporary rules to Opera's native content blocker. Rules added through this API are associated with an extension and apply as long as an extension is enabled. Once an extension is disabled or the browser is shut down, the temporary rules are discarded.

  • It defines the API that is applied to an extension browsing context.
  • An extension browsing context is a browsing context that implements the Opera extension interface (opera.extension).
  • See URL Filter API for Opera extensions


Opera adds support for the Google WebP image format.

  • This enhances Opera Turbo's compression performance with images.
  • WebP is a new image format that provides lossy compression for photographic images.

Opera Dragonfly beta 1

Opera has improved its Dragonfly debugging tool with the release of Opera Dragonfly beta 1. Opera Dragonfly covers the full debugging workflow, from inspecting network access and downloaded resources, to correcting JavaScript issues and seeing how CSS rules apply to the DOM. It supports all the newest web technologies, including SVG and HTML5 APIs such as Web Storage.

  • JavaScript debugger
    • Enables stepping through your code line by line, setting break points along the way.
    • Monitor the exact expression or specific variable in your JavaScript code.
    • Use the Break points panel to see exactly what caused a JavaScript fail.
    • Added new types of break points and more granular control.
  • CSS inspector
    • Check out what CSS rules apply to which element, and what rules are inherited or set by browser defaults.
    • Overridden rules are highlighted showing what styles are, or are not applied.
    • Use the CSS editing feature to edit existing properties and values.
    • Use the auto-complete feature to make editing faster and more convenient.
  • DOM inspector
    • Allows inspection of the updated DOM and all of its properties.
    • The DOM can be edited to experiment with changes directly in the browser.
  • Network inspector
    • Allows inspection of the HTTP request and response headers.
    • A summary of each request is shown, with the method type, response status and the time taken to be retrieved.
    • Drill down to see full details of each requests header.
    • Find latency, see how resources download and in what order, and even view cached resources.
  • Resource inspector
    • See all site resources such as images, scripts, fonts, HTML files and videos at a glance.
  • Storage inspector
    • Cookies and Web Storage can be dynamically updated, tested, inspected, and manipulated.
  • Error console
    • Allows you to see, filter and log any errors in your scripts, pointing to the exact position where the error occurred.
    • Use the Error console in combination with the other tools to hunt down and fix your site's bugs.
  • Debug your phone or TV
    • Debug pages whether they are on your computer or a supported device, such as a phone running Opera Mobile 10 for Windows Mobile.
    • You can connect to any device running Opera Presto 2.1 or above and debug using your computer's screen and keyboard. There is no need to struggle inputting test data with your phone's keypad again.
    • Opera Widgets can also be debugged via remote debugging.
  • Design utilities
    • A color picker and a screen magnifier allow you to pick out colors from a website or widget.
    • The average color of an area can be selected to make it easier to pick out colors from bitmap images.
    • Chosen colors can be stored in a palette for later access.
  • Open source
    • Built using the open web standards you know and love, Opera Dragonfly's source is available to view.
    • Not only that, but it is released on a Apache 2.0 license, meaning it is free as in freedom, as well as in beer.
    • Join in the project, or just check out the source code at the Opera Dragonfly repository.


  • Added support for phrase searching.
  • Improved CJK searches.
  • Improvements made to the panel, including a setting to disable automatic toggling

    • HTTP header: Preview-refresh: seconds
    • HTML code: <meta http-equiv="preview-refresh" content="seconds">
  • The Speed Dial thumbnail/icon is now determined using these criteria (in order):
    • Send a http header to tell the server it is a Speed Dial request
    • Detect big icons: <link rel=icon,apple-touch-icon ...> and display them instead of a thumbnail
    • Find the important part of the page (logo), and zoom in closer
