Mozilla posts Firefox 7 final to FTP
Closing tabs now directly removes those tabs from memory and leads to more resources free as time goes on.
Other changes are minor but noticeable. The address bar now eliminates the URI from the current page and highlights the primary domain to simplify spotting fake sites. Bookmark and password syncing occurs more frequently, and the renderer now supports CSS3's Text Overflow and web load time analytics for developers. Windows users now get hardware acceleration of HTML5 Canvas pages.
Another major Firefox revision is expected within about six weeks. Mozilla has entertained the prospects of a partial return to slower, major milestone releases but hasn't signaled any such change coming before Firefox 8.
