I have a steam deck and the popup covers a large part of my display area. But it doesn't need to popup every time i open a page either.

CNET is replacing the PriceBlink add-on, one which I've had for a few years. PriceBlink was out of the way and subtle, yet always showed (no clicking required) how many competing prices and coupons it had... or it was hidden when it had nothing for me. On the other hand, CNET is bright red and covers the top right of my screen, even when it has found nothing at all, and flashes like it is the greatest thing since sliced bread when it has a coupon. Just no. Uninstalling and hunting for a worthwhile PriceBlink replacement.
