Overview
Firefox is a fast, full-featured Web browser.

Firefox 7.0 Beta 4 brings a number of fixes to the memory footprint, particularly for users who like to keep multiple tabs open and iconify rather than close their web browser. Other changes include dropping http:// from the awesome bar and painting the sub-domain element of a URL in lighter grey and Bookmark and password changes now sync almost instantly when using Firefox Sync. Firefox 7.0 also support for text-overflow: ellipsis and web timing specification
