Opera works where Firefox and Gaim can`t... ???
In my faculty all computers are set as guests and have very little privilegies. Installation of programs is forbiden by administrator so portable applications come to the rescue. But Portable Firefox and Portable Gaim can`t access the internet (we have DSL)! Portable Opera works just fine but Firefox and Gaim can`t access to the internet. What can be the problem??? If Opera works why Firefox and Gaim can`t break through?
