Opera Software introduced extensions in the Opera web browser not so long ago. Before that, Opera users had access to widgets only which were displayed in their own window. This limited Opera in comparison to Firefox, and later on Google Chrome, which both enabled users to install extensions in the browser to directly interact with contents on web pages they visited.
This changed when the extensions engine was introduced in the browser which mimicked how Firefox and Chrome were handling extensions for the most part. While limited in some regards in comparison, Opera Software added the option to create Speed Dial extensions for the browser, something that Chrome or Firefox do not offer. Speed Dial extensions can display dynamic contents such as weather information, stock charts or the latest notification on Facebook on the browser's new tab page.
Two weeks ago Opera Software announced the inclusion of new extension APIs in Opera 12.1 Beta:
Extensions like Screenshoter or Goto IMDB 2 are already making use of the new APIs. Please note that you need to use Opera 12.1 to use the new functionality, as previous versions of Opera, including Opera 12.02 stable, do not include the APIs. It is likely that they will be officially released with the release of Opera 12.10. (via Techdows)Advertisement
