Is Firefox 4 Better than Microsoft Internet Explorer 9?

Firefox may be under fire from Microsoft's newly competitive browser, but with more than twice the downloads in its first day, Firefox 4 today soared over its rival by one measurement.
Microsoft, not without reason, boasted that IE9 was downloaded 2.35 million times in the first 24 hours after its release last week. And that is indeed a big number, especially for a browser that tech enthusiasts had scoffed at for years.
But less than 24 hours after its own launch, Firefox 4 cleared 4.7 million, according to the Mozilla Glow site that logs downloads.
New Features Boost Firefox 4
Indications are that Firefox 4 is gaining rapid popularity with users of the web! The reason would seem to point to the fact, that this updated browser has features, making it more appealing than Internet Explorer 9 does.
It has not taken long for Mozilla Firefox 4 to generate a huge following with millions of web users. All indications are that this momentum has yet to slow down and that Firefox 4 is ready to take on the competition, which are lining up.
The situation is that Firefox 4 are now ready to compete directly with Internet Explorer 9. It has created a quandary for some users, making them consider which they should choose. The initial perception is that Firefox 4 offers some innovative new features and is reputedly quicker. The first look though does not tell the full story, with Internet Explorer 9 reportedly greatly improved when compared to its predecessor.
However, various reports indicate that as users start researching the differences and options offered by the respective browsers, it becomes increasingly clear that the Mozilla Firefox 4 is a preference.
On of the main challenges for Internet Explorer 9 is a general perception that the browser is secure and stable and that it has still not overcome failures with the previous versions. Mozilla on the other hand, does not have to contend with an identity crisis and are therefore able to add and remove features without the risk of placing doubt in user’s minds.
Therefore, a user, rather than having concerns regarding the security, stability and performance of a browser, simply selects the one that is straightforward, without complications and has a recognized popularity, Firefox 4.

That's a lot less than the 8 million copies of Firefox 3 downloaded in that version's 24-hour debut in 2008, but that event was a heavily promoted "Download Day," and it should be noted that Firefox 4's full day hasn't finished yet.
And it does signal that at least a very sizable chunk of the Net-connected population is, in Firefox's apt phrase, choosing to "upgrade the Web." New browsers bring new Web standards, new performance, and often a new auto-update ethos that likely will lead to browsers staying continuously updated. That could simplify lives for Web developers who constantly wrangle with the difficulties of supporting old browsers.
Firefox 4 brings a raft of new features--new security and privacy options, faster loading and JavaScript, support for a variety of new standards including WebM video and WebGL 3D graphics, and 3D acceleration that extends even to Windows XP.
Mozilla expects that its arrival will lead to an increase in usage. The browser maker said it has 400 million Firefox users and counting, but as a percentage of worldwide browser use it has lost share to Chrome, which now accounts for more than 10 percent of usage worldwide.
Those who currently use Firefox can upgrade to the new browser by clicking on the help menu and selecting check for updates. Firefox 4 is available for Windows, Mac and Linux.
Firefox was created by Mozilla as an open source software project and is shared and downloaded for free. Famed for its speedy web page loading and security, Firefox quickly became one of the most popular browsers available. The browser became the most used back in 2009 when it overtook Internet Explorer.
