For some months now this site has popped up a warning message to users of old versions of Internet Explorer (i.e. less than version 6.0, or any version on the Mac), encouraging them to upgrade. It links to the latest version of IE, but also mentions Firefox, Safari and Opera and links to the Browse Happy site.
Today I updated the script to improve its handling of users of IE 5.5 (who weren’t previously getting the message) and also notify users of Firefox 1.0.x that they should update their browsers. Although 1.0.8 was released very recently, it was the last in the 1.0.x line and in future users should move to 1.5.x and higher. The upgrade notifications aren’t very obvious in the 1.0.x line so some users may be unaware that a new version is available so hopefully this will encourage a few converts. Around 4% of the visitors to this site in the past week were using obsolete browsers – most of them 1.0.x versions of Firefox.
The message is not shown to Internet Explorer 6 users. These make up for 45% of my visitors even now and I do not want to alienate them for the sake of browser fanboyism.
