Four Reasons Firefox 4 can make a go of it--And one reason why it can't.

With Internet Explorer 9 running faster than ever, and Chrome looking cleaner than ever, is there room for Firefox 4?
Written by Steven Vaughan-Nichols, Senior Contributing Editor

In 2004, Internet Explorer (IE) 6 was already a security nightmare but since Microsoft has stomped all over Netscape and alternative browsers like Mozilla, now SeaMonkey, and Opera had little traction, Windows users pretty much stayed with IE... until Firefox appeared. It was a breath of fresh air. IE users concerned with security and open-source fans quickly flocked to the new Web browser, and over time others followed. But, in the last few years, Firefox lost some of its luster. Can Firefox 4 restore it?

Now that Firefox 4 has been released a day early, albeit after months of delays, I asked myself if Firefox 4 really was, not just better than the Firefox 3.6.x series, but it's more serious competitors: IE9 and Chrome 10.

To see how it would do I've been running the Firefox 4 betas, release candidates, and just now the final, on Windows 7 SP1, Windows XP SP3, and the Mint 10 Linux distribution. For XP and Windows 7, I used a Gateway SX2802-07 desktop. This PC uses a 2.6GHZ Intel Pentium Dual-Core E5300 processor and has 6GBs of RAM and a 640GB hard-drive. For my Linux Firefox box, I used a Dell Inspiron 530S powered by a 2.2-GHz Intel Pentium E2200 dual-core processor with an 800-MHz front-side bus. This box has 4GBs of RAM, a 500GB drive. This is what I found.

1. Operating System and Application Interoperability

Firefox 4, unlike IE 9, will run not only on any version of Windows-IE 9 is Windows 7 and Vista only-but on pretty much any desktop operating system. Of course, that's also true of Chrome and many of the other browsers. Unlike the others though, Firefox also supports a gigantic family of browser extensions.

If there's anything you want to do with a browser, but it's not built-in, there's almost certainly a way to do it with a Firefox extension. I found that most of the extension I use every day with Firefox, such as the newest versions of the LastPass password manager; the Xmarks bookmark manager; and the Google toolbar work just fine with Firefox 4.

Not all add-ons will work so smoothly though. There have been many changes in how Firefox handles extensions. I know some extensions will fail until they've been updated. I was also annoyed to find that I had to close and restart Firefox to get most extensions to work.

2. Speed

For pure speed, according to the SunSpider JavaScript Benchmark 0.9.1, 32-bit IE 9 is still the winner at 251.5ms (milliseconds) on Windows 7. Firefox did, to my surprise, come in faster than Chrome with a rate of 300.5ms. Chrome came in just behind it at 317.1. Other tests though show it to be a closer race with something to be said for each browser. Firefox's new found JavaScript speed can be credited to the Jägermonkey JavaScript Engine.

Speaking as a user Chrome still feels faster to me, followed by IE, and then, I'm sorry to say Firefox. Still, Firefox 4 feels much faster than Firefox 3.6x. Your usage may vary.

I was also pleased to see, after multiple hours of use and many tabs opened and closed, that Firefox finally seems to have fixed its infamous memory leak problems. This often led to system slowdowns, and in extreme cases, even to crashes. That, knock on silicon, now seems to be a thing of the past.

3. Web Interoperability

Firefox 4 does a much better job than IE 9 when it comes to Web standards compatibility. On the Acid3 Web standards test, Firefox 4 came in with a score of 97 compared to IE 9's 95. On the HTML 5 compatibility test, Firefox had a good score of 255 compared to IE's 130. Unfortunately, Chrome does better than both. Chrome had an Acid 3 score of 100 and a HTML 5 mark of 288.

In practice, I didn't find any Web pages-except for those sad sites still stuck in IE-6 comparability hell-that gave Firefox 4 any problems.

4. Features

There are a lot of features to like in Firefox 4. A very short list of the ones I like includes Firefox Sync. If it could work across browsers, it might replace my current bookmark and password favorites: Xmarks and LastPass. If you don't change browsers though, Firefox Sync might be all you need.

I also like tab grouping. This, like the name suggests, lets you group tabs together. It's perfect for keeping tab 'families,' like say one group for "social networking" and another for work.

A related feature, which I'm already fond of, is Firefox's ability to turn Web pages into pinned "applications". All you need do is right click on a tab to turn it into an application, and, until you change your mind, the page will always be available when you start your browser. This is ideal for pages such as Gmail that you know you'll be opening over and over again during the course of the day

5. And what's wrong

Firefox is full of good stuff, but even taken all together is it good enough to bring back users who have moved on to Chrome, or back to IE? I don't think so.

It is faster than it once was. It is better than it once was. It has many new and useful features. But, it's in a dead-heat with the other browsers when it comes to speed. And, yes, it is better, but then so are the others. As for the features, many of these, such as pinning, were already available in other browsers.

I'll also add one possible problem. I happen to like the Chrome-style of a minimal Web browser interface. Now that everyone, including Firefox, is copying it though I really wonder if it's this clean interface is for everyone. I suspect a lot of people like having the controls easily available lined up on the top of the program even if they do use up some of screen real-estate.

Had Firefox shown up on time, in 2010, it might have been a different story. Today, though, I fear it's a case of too little and too late for it to be a contender in 2011. I see Firefox continuing its slow decline to the rise of Chrome in users hands, while IE 9 will, for a time at least, will stabilize IE's generally declining market share. Eventually, I foresee Firefox becoming the number three Web browser with IE and Chrome fighting for the top prize.
