Inside the extension lives `keepa.js`. A notable file and it preforms its duties well. I enjoy using this extension but I have to make personal modifications.

1. Disable Bug Reporting (Telemetry)
reportBug:function(a,b,f){}

2. Disable Background Scraping (The "Botnet" Feature)
108108==b.timeout?(b.stockData&&(c.stockData=b.stockData)):(b.domainId&&(aa=b.domainId));};

3. Disable Invasive Stock Checking (Session Hijacking)
initStock:function(){}

4. Stop Sending Browsing Data
case "sendData":f({});break;

Since keepa is eula I cant share my derivative of keepa. They have no option to disable any one of these invasive features. If you really want to you have to edit the source code by hand like I have done. I will change the review to 5 stars if they choose to make these changes a toggle and change the license to GPL 2.
