    The future of Firefox
    It is worth noting that the release policy has been revised new versions. Now, significant versions will not be so large-scale, for which they will often come out, about once every 4 months.

    In Firefox 5, it is planned to add:
    new account management interface (in the picture are rough sketches from the UI development unit)
    Although I would have had just this (maybe someone blinds after 4 and a half months!?!) a
    simple interface for exchanging links with friends (F1 service integration) to
    implement animation effects in the user interface to
    prepare a 64-bit build for Windows.

    In Firefox 6: the work will be focused on expanding the capabilities for ensuring the operation of web applications ( Open Web App project ), increasing the performance of the cache and JavaScript engine, preparing the assembly for Mac OS X 10.7.

    In Firefox 7: it is planned to continue work on ensuring the isolated execution of various browser subsystems (the user interface and the processing of content in different tabs will be processed in parallel , by different processes) and integrate support for XBL (XML Binding Language) .
