Earlier this year when it announced the intention to ship Firefox 5.0, Firefox 6.0 and Firefox 7.0 by the end of 2011, Mozilla also unveiled some of the features it had planned for introduction this year. The open source browser maker did warn that the Firefox Roadmap for 2011 was not finalized, and it appears that changes have already been made.

Mozilla removed all the mentions of new features for Firefox 5.0 and later, slapping the “To Be Announced” status on all.

Users that want to see what the company had planned initially can read my initial article on the upcoming features.

At the same time, there is a collection of details under the “So, what are we building?” section of the Roadmap.

Future versions of Firefox will continue to be customizable, will synchronize across devices and put users in control of their information. Of course, the browser will also not diverge from its open source path and allow contributions from the community.

Details around the evolution of the JavaScript engine are also to be announced at a later date, however, information has already been posted on add-ons, plugins, customizations, developer tools, and distribution.

Here is a list with additional modifications:
