/:16 Windows/Mac/Linux: Firefox 4 Beta 5 is out tonight, and it firms up a few things that have been slowly taking shape in previous betas of the browser. Most significantly, it enables by default the (Windows-only) hardware acceleration that had been available through a deep settings switch previously. New to the build, however, are a robust audio API (demonstrated at YouTube), a return to two-column menus, this time with multiple shades, and a new feature, HTTP Strict Transport Security, that allows sites to demand a browser make a secure and encrypted HTTPS connection. Grab the just-out beta and tell us what you think in the comments. [The Mozilla Blog via CNET]
