Mozilla and all their fans, and FOSS people in general, are fond of saying that Firefox has had over 25 million downloads. Sounds like a lot, right?
I was on the Skype site earlier today. We use it at work in preference to calling mobile phones. (I was on the site because users were having trouble logging in – some kind of authentication server failure.) Skype are currently reporting 84 million downloads, and one million users using SkypeOut, the Skype-to-PSTN service.
Is Firefox really all that popular, then?
