I shall stay on topic. As far as I know Opera is the only webbrowser that has an extra security layer, a master password.
- Will the master password make the browser more or less secure? You only need to answer yes / no.
- I can not see that you have made a singel fact of why FireFox is more secure than Opera when you shop online.
- I have made many for Opera. Reread the thread if you don't find these facts.
