Several hours after Microsoft announced a March 14 release date for Internet Explorer 9, Mozilla this afternoon announced the availability of the release candidate for Firefox 4 for Windows, Mac and Linux. That’s the last major step before the final release, although the timing of the finished version will depend on how well the RC is received by the people who use it.
See this rundown for more about the features of Firefox 4, including a new location for tabs, above the address bar; hardware-accelerated graphics turned on by default; improved synchronization of settings, bookmarks and other data across multiple devices; and support for WebM video.
People already using the Firefox 4 Beta will be automatically upgraded to the release candidate, according to a Mozilla blog post. I’m downloading the RC now — if you try it, let us know what you think.
