Last Friday, an agency of the German government issued a warning against the use of Internet Explorer. What has been the impact on Firefox and the Mozilla community? Looking at the chart below, we can see that over the past few days there has been a huge increase in the number of Firefox downloads from IE users in Germany. The orange area is meant to represent the “incremental” impact, i.e., the number of downloads beyond what we would have normally expected on those days. As the chart highlights, the orange area adds up to just over 300,000 downloads during the recent Friday-Monday period.
