Hi, the extension wouldn't be able to not show blank pages because amazon is the entity splitting products between pages. To see only new products, we have the Alert and Explore queues. About being asked to log in again multiple times, check if you are not changing between "desktop" and "mobile" mode frequently or if you are using VPNs or proxies. Amazon may ask for log in again when detecting that you are using a "different browser" and those scenarios are identified as this.
