Get Firefox to ask confirmation when redirected from https to http?

Some websites with only partial HTTPS support will automatically redirect to an unencrypted version of the page. Firefox does not give a warning or ask confirmation before fetching the unencrypted URL, which I consider to be a security issue. An example is https://www.amazon.com/ which will silently redirect to http://www.amazon.com/. Is there a setting I can change to make Firefox ask confirmation before following Location headers?

This won't answer your question, but have you tried add-ons like HTTPS Everywhere?

You can also try the following, but will probably give you more headache than its worth depending on the sites you browse:

  • Edit (or New Fx Menu) > Preferences > Advanced > General
  • Select "Warn me when sites try to redirect or reload the page"

Thanks Cory, but HTTPS Everywhere won't help and I already have the suggested preference enabled; it doesn't work for 3xx Location redirects.

I tried an addon called noredirect but it doesn't work, presumably because it's three years old. Does firefox really require 4gigs of ram to compile? I'd try writing a patch but I'm using a netbook (512M ram)
