SSL only firefox add-on?

I want the HTTP URLs to be blocked entirely, so that it is not passed on to

But I still want the HTTP URL to be in the Firefox URL bar, so I can try if
https works (by adding the "s").

If it doesn't then I can disable it on that URL.

However if I redirect it to a page on my local host, won't it come like this
in the Firefox URL bar C:\block.html ?

Basically I guess I am looking for something that the corporate firewall
did...I think it did that because all the company resources to do work was
on https website, and there was no need to surf the interwebs...and in those
days there was no https Google....
