'Namoroka' is the code name for next Firefox 3.6 development. The version number will be initially set to "3.6", but this should not be considered final, and as such the project may also be referred to as "Firefox.next".

"Namoroka will be based on Gecko 1.9.2, with an intended release target of early-to-mid 2010. As always, we will only release the finished product when it's ready."

Namoroka will focus on the following areas:

Performance
Observable improvements in user-perceptible performance metrics such as startup, time to open a new tab, and responsiveness when interacting with the user interface. Common user tasks should feel faster and more responsive.

Personalization & Customization
Simplify the development, discovery, installation and management of browser customization and functional extension. Where possible, provide a custom fit user experience based on a user's interaction history. Act in the user's interests, leveraging existing knowledge about their identity and browsing habits.

Task Based Navigation
Allow users to organize their tabs, history, downloaded files, and other resources according to the task they were attempting to accomplish. Provide support for executing common web-based tasks, mash-up style, without having to visit a website.

Web Application Support
Blur the distinction between web and desktop applications, providing web developers with the tools required to create rich application experiences for a user who is connected or disconnected from the Internet. Act as the intermediary between web applications and the user's OS desktop.

System Integration
Integrate with the look and feel of the host operating system, including data-level interactions with existing system services such as dictionaries.
