Mozilla Firefox continues to grow across Europe

Almost one year after its third version release, Mozilla Firefox continues to grow versus Internet Explorer, particularly in Europe. The red panda becomes the most successful alternative web browser. For this study, we were interested in used browsers and we estimated traffic distribution registered on websites for 23 countries.
  • Study carried out from November 1, 2008 to April 30, 2009
  • Cross section of 15,248 websites
Internet Explorer drops by almost 4 points, Firefox jumps about 2

The table below shows traffic distribution by browser, an estimate of the average distribution registered on websites in Europe over the last 6-month period.

Internet Explorer dropped steadily by almost 4 points during the last 5 months:

  • On average, in a European country, IE visit share dropped from 67.2% in November 2008 to 63.6% in April 2009, in other words almost a 4-point loss.

Mozilla Firefox jumped about 2 points in 5 months:

  • Firefox climbed from 26.4% in November 2008 to 28.4% in April 2009. It recorded the strongest progress: 2 points in 5 months.

Even if Chrome share doubled since November, it remained below 2%:

  • Since its release, Google browser hardly established itself in the market with a 1.7% visit share in April 2009.


Mozilla Firefox more convincing in Germany

The average share of Mozilla visits registered on websites in 5 European countries (Germany, Spain, France, Italy and United Kingdom) is represented below. For each country, we analyzed traffic website generated in the countries studied.

Mozilla Firefox registers twice as much traffic in Germany than Spain, Italy and United Kingdom:

  • The browser accounts for 42.2% of web traffic in Germany, 1.5 times more than European average.
  • France slightly exceeds European average with a 30.6% share.
  • In United Kingdom, out of 6 visits, 1 is attributed to Firefox, 1 out of 5 visits in Spain and Italy versus 1 out of 4 visits in Europe…


Firefox share continues to soar and grabbed 4 points in 5 months:

  • Firefox's current 42.2% visit share is up from 38.2% in November 2008, in other words a 4 point-rise.

Lower but steady gross increase for other countries (Spain, France, Italy and United Kingdom).


IE is more popular on weekdays, Mozilla on weekends…

IE’s market share declines substantially on weekends:

  • On average, in April 2009, IE visit share drops by 4 points on weekends for websites in Europe compared with weekdays visit share (60.1% on weekends vs. 64.4% on weekdays).
  • People may use IE at work, and choose to use Firefox at home. Many businesses have only IE on their machines, boosting Microsoft's share.

Firefox, Safari, Opera, Chrome and Netscape usage share are often higher on weekends:

  • On average, in April 2009, Firefox accounts for 30.6% of traffic on weekends and 27.9% on weekdays.

  • With 22.8%, Safari records the strongest relative deviation regarding Firefox’s visit share between weekdays and weekends usage.


The result is obvious: Firefox grabbed a little more market share from Internet Explorer and is ahead for home use.

The latest release of Internet Explorer in March 2009, IE8, delivers better standards compliance and has many new additions: in April the trend has not been reversed!

Stay tuned as AT Internet Institute (ex-XiTi Monitor) will provide a new browser barometer soon.


The 23 countries included in the study were:
Austria, Belgium, Bulgaria, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Luxemburg, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Spain, Sweden, Switzerland and the United Kingdom.

For each country, we analyzed traffic website mainly generated in the countries studied. We calculated an average traffic distribution by websites. The visits’ share for each browser is the total number of visits of the analyzed browser compared to the overall number of visits for all browsers combined over a given period.

The Europe indicator is representative of the countries audited. The average visits’ share in Europe is the average of the indicators for the 23 countries studied. Country influence is homogeneous.
