Amazon search by "Featured" not changing to "Low to High price"

Hey Vintage, this issue is caused by the ClearURLs addon sadly. I don't think there's a way to whitelist that part of Amazon because the addon doesn't have a whitelist feature. Please uninstall it. I recommend using the Neat URL addon instead: https://addons.mozilla.org/en-US/firefox/addon/neat-url/ To uninstall ClearURLs: [[Disable or remove Add-ons]] But make sure to watch for any weird breakages with Neat URL. These addons are great since they make our lives easier and clean up ugly looking urls but they may also break things accidentally. Sadly ClearURLs breaks other things on other websites too. So just make sure to keep watch on Neat URL & disable it if you ever encounter a weird issue on a website.
