The browser Firefox is getting a lot of attention lately because they've asked the Ubuntu people to stop shipping their modified version with the "Firefox" symbols. Ubuntu will be naming it "IceWeasel".
Not everybody remembers that there used to be a Firesomething extention for Firefox that allowed you to change the program name, or for it to change randomly. It can be a lot of fun. The developer has stopped supporting it, but apparently the extension can be modified to work with version 2.0, so we can have the fun all over again.
The joke here is that the Firefox team had to change the name a couple of times early on, so as not to conflict with extant products.
