July 13, 2010, 2:04 PM — While it's impossible to sum up the thousands of enhancements and bug fixes both big and small, the Firefox 4 beta version brings the browser that much closer to taking over everything on the desktop. There are fewer reasons for anyone to interact with an extra plug-in or the operating system. Remember when people cared about whether a machine was Windows or Mac or a Commodore 64? Remember when software needed to be written in native code? Those days are fading away quickly as the browser is more able than ever before to deliver most of the content we might want.

There are plenty of other little parts of HTML5 that have been slowly arriving in previous versions of Firefox but are now being more fully integerated. MathML and SVG data are now a bit easier to mix right in with old-fashioned text. The Canvas and optional WebGL layers can create custom images at the browser without waiting for a server to deliver a GIF. A handful of new tags like <header> and <figure> offer a more document-centric approach, so the browser can present information more like the data on the printed page. The <figure> tag can be matched with a <figcaption> tag and the browser will keep the two together and try to put the results near the <mark> tag.
