I've recently started seeing sites break, and I see random Cross-Origin Request Blocked errors in the browser console. This appears to have caused some issues on Amazon. 1 star because it breaks sites, but +1 star because it *does* do what it advertises.

Comparing to this same extension on Chrome: In Firefox, I cannot for the life of me figure out how to get the icon to display, cannot modify the affiliate link permission, and cannot modify the site permissions.

This script for some reason blocks the Seller's Description for every listing on eBay. In Chrome this can be resolved by removing permission for eBay sites; In Firefox, this permission can't be accessed, which makes eBay unusable.

I've done a lot of searching and found no way to resolve this in Firefox. If there is a way I will happily update this review. Until then I can't recommend this add-on for Firefox, at least for anyone who uses eBay.
