Hello I know C# and VB.net as well as PHP, however my Javascript is very very basic as I never had the need to use it that much. I wanted to develop a script that would run on google chrome console which would compare item names between 2 tabs and also compare their prices. Is this possible to do? Example: Site 1 loads their items let's say "Laptop H666" for the price of 700$ Site 2 loads their items and it also has a "laptop H666" for hte price of 600$ The script would create a notepad or show a popup of all the items that have a substancial difference in price(remember this is server sided, it's just a way to show me the actual difference and such) Is such a thing possible / hard?
