Student given detention for using Firefox

An anonymous reader writes: Several sites are reporting that a student has been given detention for using "Firefox.exe" to do his classwork. No, really. The student was in class, working on an assignment that necessitated using a browser. The teacher instructed him to stop using Firefox and to do his classwork, to which the student responded that he was doing his classwork using a "better" browser (it is unclear whether the computer was the student's own computer or not). The clueless teacher (who called the rogue program "Firefox.exe") ordered him to detention.
