In the past I’ve blogged a few times about Firefox’s continued rise in market share, and this week it was announced that the trend continues. I immediately compared the new statistics to previous blog posts and came to the conclusion that the information doesn’t always come from the same source, as the figures jump about a bit. The latest information shows that Internet Explorer has fallen to 59.9% while Firefox now boasts 24.5%. So this doesn’t tally with data from StatCounter but does follow the trend reported by NetApplications.

However, that’s a less than 1% rise for Firefox since October 2009, but a 5.8% decrease for Internet Explorer. So where has the market share gone? One would assume it’s gone to Google’s Chrome, but could it have jumped 5%?

From now on I’m just going to look in one place, and that’s here.  The figures tell us that since June 2009 Internet Explorer lost 8.37%, while Firefox gained 2.16%, Chrome gained 4.33% and Safari gained 0.93%.

What I find interesting is that both Microsoft and Google have thrown money at advertising their browsers, both free products. A few months ago there were some big Chrome posters in key positions in London – for Google it has to be about mind-share. At the moment, Microsoft are running adverts for Internet Explorer on television – is this to try to stem the market share leak? One of the adverts shows a generous man shopping on-line for gifts for his missus, and extols the benefits of private browsing. That’s something that Internet Explorer’s three big rivals can do too, so if they were trying to differentiate themselves Microsoft wasted a big pile of money on that one.
