It is not necessarily from amazon.com
You will need to look at the url being detected and add that to the Adblocker (Settings > Internet Downloads > Advanced > Adblocker)
You can see this by selecting the entry that you don't want to be captured and then Main Menu > Properties
See the source field below. This is for a youtube video, so in this case, I would add googlevideo.com to the Adblocker. From then on, no streams who have a source url containing googlevideo.com would be detected.
I want to stop the media recorder from trying to down load from amazon.com while in stream capture mode. I have added amazona.com to my HTTPS Protocal setting as 'Do not pass the following urls throught the https/ssl monitor:' and I thought that was working but lately if I have amazon on while I using the stream recorder it starts trying to download from amazon. I tried adding amazon.com to the add blocker but that did not work either.
