Web Applications do not take questions about Firefox extensions, for the obvious reason that they're not about applications related to the web. It's about Web Applications, i.e. server-side.
Firefox is a desktop/client app rather than a server app.
They don't like them on Web Apps:
- Reason for my question better suitable to superuser than here?
- colorzilla extension doesn't work in Firefox 12, Any good alternatives?
And they're getting closed on Super User too:
