What is this script:
When you opened many amazon tabs on your browser and keep them opened for a while, they seem to be calmly in idle state. But it's not true.

Every single amazon shopping page launches bunch of automatic tasks for some kind of purpose, a marketing analysis or tracking your behavior, I don't know, for literally more than a HUNDRED times total per every single second. Even if your browser modestly reduces its frequency on background tabs, it does cost on your CPU. And you keep tabs more, the cost also gets more. You can check them with browser's task manager.

This script reduces its frequency of needless tasks to at most 1 time per minute for reducing the CPU load. And surprisingly you loose NOTHING at all. You can enjoy shopping completely with no differences but much tamed CPU. What the hell was that?

Before (Firefox, 1 foreground tab, 3 background tabs, opened for a while)

↓
After


* The effect seems to depend on browsers. The CPU load and its reduction are significant especially on Firefox.
* I haven't tested its effect on any other amazon services than shopping though, I appreciate your reporting.
