Firefox Loses Browser Share Third Month Running

Meanwhile, Google's Chrome continued its climb for the 16th straight month and Microsoft's IE hit yet another record low in browser share

Mozilla's Firefox lost share in February, the third consecutive month that the browser has slipped, according to metrics data published today.

Google's Chrome, meanwhile, continued its climb for the 16th straight month.

Firefox lost about 0.2 of a percentage point last month to end with a usage share of 24.2 percent. It was the third month in a row that Mozilla's browser fell in the rankings posted by Web measurement vendor NetApplications.com. Previous dips in Mozilla's share were one-month blips; this is the browser's first sustained decline in NetApplications' numbers.

Since the end of November 2009, Firefox has dropped nearly half a point, representing a fall of 2 percent of its total share.

NetApplications is not the only metrics company to note Firefox's slump. The most recent data from Irish vendor StatCounter, for example, shows an even larger drop of 1.2 points -- or 3.6 percent of its total share -- since November.

The slide came even as Mozilla converted a sizable chunk of its Firefox 3.5 user base to the newer Firefox 3.6, the upgrade that shipped in late January . Last month, Firefox 3.6's share surged by nearly 4 percentage points to 5.1 percent. Meanwhile, Firefox 3.5's share fell 2.5 points to 14.6 percent, and the even older Firefox 3.0 dipped by 1.6 points to 3.6 percent, its lowest share since the month it was released in 2008.

As Firefox slid, Google's Chrome again boosted its share, although the increase was smaller than in the two months before. Chrome ended February with a 5.6 percent share, up 0.4 of a percentage point. Chrome has doubled its share in the last six months.



Internet Explorer (IE) lost a half percentage point last month to finish with a share of 61.2 percent, yet another record low for Microsoft 's browser. The upside is that IE's decline in February was under its 12-month average drop of 0.6 of a percentage point, and the smallest in a year. Microsoft may, in fact, find some comfort in NetApplications' numbers: IE's slide may be slowing. In the last three months, IE lost 2 percentage points, while during the three-month period immediately before that the browser slipped by 3.4 points.



Apple 's Safari posted a slight decline to 4.4 percent for February, while Opera Software's desktop browser essentially remained flat at 2.4 percent.

Not surprisingly, Microsoft's nearly-nine-year-old IE6 again fell in NetApplications' usage measurements, ending last month at 19.8 percent, down 0.2 of a percentage point. The newer IE7 lost more than four times more share, falling 0.9 of a point to 13.6 percent. IE6's decline was well under its torrid pace of the previous four months, when it lost more than a point per month.

But IE6 continues to get the hook from notable Web sites. Last week, YouTube announced it would stop supporting the aged browser starting March 13; as of that date, the popular video site won't guarantee that new features will work in the browser.

On Thursday, a Denver Web design firm will hold a funeral for IE6 . Aten Design Group was forced to change the location of the mock event after it received more RSVPs than its small office could accommodate. "Even more people want to see IE6's cold, dead body than we imagined," the company said on the ie6funeral.com site it set up.

IE8 captured only a sliver of its siblings' losses: IE8 ended February with a share of 22.5 percent, up just 0.1 of a point, the smallest increase since January 2009, two months before the browser's official release, and at a point when only a release candidate was available to the public.

When NetApplications accounted for IE8's "compatibility view" -- a feature that lets users display sites as rendered by the older, and often Web standard-incompatible IE6 and IE7 -- Microsoft's newest browser owned a 25.8 percent share, making it the most popular single edition of any browser by a six-point margin.

IE's losses could pick up this month with the broad introduction of a browser ballot in the European Union beginning this week. The ballot was mandated by an agreement Microsoft reached last year with EU antitrust regulators nearly two years after Norwegian browser maker Opera filed a formal complaint. The ballot appears on Windows PCs where IE is set as the default browser, and lets users download and install rivals, including Chrome, Firefox, Opera, Safari and others.

Although Firefox has traditionally been the browser to reap the most reward from IE's persistent decline, Chrome now occupies that place. Over the last 12 months, Chrome has outgained Firefox by more than 2:1, posting an increase of 4.1 points to Firefox's 1.7 points. If Chrome keeps up the pace of the last three months, it will break the 10 percent mark in October, 11 months ahead of a goal it set last year.

NetApplications.com measures browser usage share by collecting systems data from the computers that visit the 40,000 sites it monitors for clients.

Google Lays The Groundwork for Extensions in Chrome

Google is getting ready to offer widespread support for extensions in Chrome, launching a program which will allow third-party developers to add features to its browser.

The company released more details about its new Chrome Extension Gallery Tuesday. Developers can now upload their extensions to the Chrome Extensions Gallery, in effect publishing their extensions even before the browser officially supports them. Support for Chrome extensions is available in the current developer release, but they will probably arrive in the browser for all users before the end of the year.

At the moment, there isn’t much to see in the Chrome gallery — it’s just a form for developers to upload their extensions. However, Google is clearly hoping Chrome will one day support an extension ecosystem similar to the one Mozilla enjoys with its highly successful add-ons community for Firefox. The site will offer the ability to search and browse for extensions, and Google is encouraging developers to upload videos and screenshots explaining what each extension does.

The company has also posted guidelines outlawing things like copyright infringement, hate speech and any extension to “enable the unauthorized download of streaming content or media” — which means we probably won’t see extensions for ripping videos from YouTube.

To that point, Chrome extensions will be reviewed before they become publicly available. The Chrome Blog says that, for most extensions, “the review process is fully automated.” However, if your extension plans to use low-level components or access file:// URIs, Google will require a manual review and may ask developers for additional information before such extensions end up in the gallery.

Firefox: Heat And The CPU Usage Problem

Firefox has a CPU usage issue and, consequently, can cause overheating problems in some laptops, particularly ultraportables. That's what I've found over the last couple of years.

But don't take my word for it. This is documented on a Mozilla support page entitled "Firefox consumes a lot of CPU resources." The page states: "At times, Firefox may require significant CPU [central processing unit] resources in order to download, process, and display Web content." And forum postings like this one about a Dell Netbook are not uncommon: "Mini9 would get way too hot."

The Mozilla support page goes on to say that "you can review and monitor CPU usage through specific tools" and describes ways to limit CPU usage, such as: "A Firefox add-on, called Flashblock, allows you to selectively enable and disable Flash content on Web sites."

Let me describe my experience. I find that tab for tab, Firefox uses decidedly more resources than other browsers--Safari, for example. And in the past (when I was actively using a Windows Vista-based machine) Firefox also compared unfavorably with Microsoft's Internet Explorer for CPU usage.

More specifically, here's the behavior as I see it. When I'm accessing sites with multimedia content such as the CNET front door, Firefox CPU usage will bounce around between 30 and 60 percent, and sometimes spike higher (80 percent and above), as indicated by the Mac OS 10.6.2 Activity Monitor.

On the other hand, the Safari CPU usage with the same pages open is much lower--typically between 2 percent and 10 percent.

My theory is that most users don't notice this because in mainstream laptops, this isn't an issue. But it can become an issue in ultraportables--typically under an inch thick--which are more sensitive to heat because of the design constraints. The ultrathin Apple MacBook Air, which I use as my main machine, is a good example.

The fan is usually an audible indicator of CPU usage issues. When I'm using Firefox and I have tabs open on multimedia-rich sites (which is par for the course these days), the Air's fan will almost invariably kick on and stay on until I close the tabs. As I write this, the fan has finally shut down after I closed the Firefox tabs (e.g, CNET front door). Those same tabs in Safari are still open and not causing any significant spike in CPU usage or fan activity.

When I contacted Mozilla, a technical support person guessed that Safari is possibly better at optimizing Flash-based sites compared to Firefox. And that may be true. However, I had similar issues before when I was using a Hewlett-Packard business ultraportable (also very thin like the Air) that were not necessarily tied to Flash usage. In short, Firefox was less efficient with CPU usage compared to Microsoft's IE 8. And the behavior was similar. The HP laptop would quickly heat up and the fan would kick on.

Finally, let me reemphasize that I'm guessing that most users don't notice this because heat dissipation is not a big issue for mainstream laptops that are not necessarily thermally-challenged when accessing multimedia-rich Web pages. That said, this has been a steady problem for me because I use ultraportables almost exclusively and has forced me to limit my use of Firefox.
