Userscripts are alive and well! I use Tampermonkey in conjunction with an Amazon seller extension (which I won't name because I'm not really using it as intended). The extension displays, among other things, a flag icon next to a product listing indicating the seller's country. My script hides the extension's entire UI and replaces it with a country filter. It can be really useful to filter down to US sellers only, and only see brands that are well established here
