updated to add support for primevideo.com

Adjusted a bug

Further adjusted the setting to fix a bug that popped up

I've changed the method that the code uses to detect the Element prior to disabling it in a way that is more reliable.

I have increased the scope from just amazon.com to include major amazon domains as follows:

"*://*.amazon.com/*",
"*://*.amazon.co.uk/*",
"*://*.amazon.co.jp/*",
"*://*.amazon.ca/*",
"*://*.amazon.com.au/*",
"*://*.amazon.de/*",
"*://*.amazon.fr/*",
"*://*.amazon.it/*",
"*://*.amazon.es/*",
"*://*.amazon.in/*",
"*://*.amazon.com.mx/*",
"*://*.amazon.com.br/*",
"*://*.amazon.cn/*"
