Ubuntu’s current release version of Firefox 3.5 is named Shiretoko and sends a user-agent of Shiretoko/3.5 rather than Firefox/3.5. This broke a number of sites I use that rely on browser sniffing such as Facebook Chat and DailyMotion. There are two ways to adjust this behavior:
1) Type about:config in the address bar. Search for ‘general.useragent.extra.firefox’. Double click “Shiretoko/3.5″ replace it with “Firefox/3.5″
2) Use the User Agent Switcher plugin. This I prefer this option as it also lets me set IE user agents so I can use a few sites that think they require IE, and also set iPhone header’s for development.
