Firefox Thankful for Strong November

Firefox use in the United States climbed 34 percent in the last month, according
to a report published by Web analytics company WebSideStory Monday.

The report comes hours after the Mozilla Foundation, an open source
organization working on several consumer-based applications, announced it
had reached the 10 million mark in downloads for its Web browser.

Firefox is a standalone Web browser based on the Mozilla Suite version
1.7.5, a combination browser, IRC chat, e-mail and newsgroup client and HTML

San Diego, Calif.-based WebSideStory only this summer started tracking
Firefox numbers, separate from Netscape and Mozilla-based browsers, but has
seen a steady rate of growth in that time. In the last month, that growth
has increased: November’s 34 percent growth is noticeably larger than
October’s 13 percent jump.

Officials credit much of last month’s growth to the launch of Firefox
Nov. 9, which saw 5 million downloads in 11 days and 10 million
by Sunday.

According to WebSideStory numbers, Firefox’s gain was made at the expense of
Microsoft’s Internet Explorer (IE), the long-dominant
browser in the market, which slipped more than a percentage point.

Geoff Johnston, an analyst at WebSideStory, said the impact of the numbers
depends largely on who’s reading the report. IE still maintains more than
90 percent of the browser market, while Firefox use is little less than five
percent. He said people shouldn’t set their hopes on seeing another browser
war, like the one between IE and Netscape in the 90s.

“If the question is, ‘are we heading down to a true browser war’ where we’re
neck and neck at 50/50 [browser market share], I don’t think that’s ever
going to happen again,” he said.

Johnston said there IE was able to drive Netscape out of the market in the
first place was largely because it was better; in the case of IE 5 versus
Netscape 4, significantly better. This time around, Netscape’s successor
doesn’t have the clear advantage, and the security issues that have beset IE
in recent times won’t be enough to make the switch to Firefox a
“no-brainer,” he said.

“What we may see, though, is a significant sub-culture of people who use
[Firefox] and are loyal to it as an alternative to Internet Explorer,” he
said. “The question really is, then, where will that stop — will it stop
at five percent, 8 percent or will it make it all the way up to 15 percent?
That’s hard to say. All we know for now is that for the last six-plus months,
it’s been growing at a consistent rate.”

Numbers have varied in browser market share. Earlier this month, another Web
analytics company, Dutch-based, reported IE market share down to
88.9 percent, with the Mozilla browser at 7.35, though Johnston had issues
with the findings at the time.

The browser stats page at gives even bigger credit to the
browsers at the Mozilla Foundation (they aren’t broken down by Firefox and
Mozilla Suite); the site’s December numbers show Mozilla has 21 percent of
the market and IE at 71 percent.
