Firefox – How to Reset RSS Feed Handling

As a developer I want to view the raw RSS feeds from my application.

But Firefox keeps taking me to a Google page and wants me to tell whether I would like to subscribe in Google Reader or Google IG

I'm desperately seeking the button labeled "just let me view the raw RSS feed" button.

Very annoying behaviour. And "View Source" lets me view source on the actual google page.

Any suggestions on how to bypass this feature/annoyance in Firefox?

PS. I am aware that I probably once upon a time accepted a setting. But there is absolutely no clue on how I disable that setting again — even though it's probably my own fault.
