What does the sniffer in the Awesome Screenshot chrome extension target?

Question

Google Chrome

Good afternoon!
I accidentally noticed this thing, in injections on arbitrary pages:
Source pastebin.com/PiVuZbr7

It looks like a sniffer, but why is there a search for phones on the page? Help me understand what exactly the sniffer is aimed at? At the same time, if this is definitely malware, help to cut out this extension by complaining on the page in the google webstore
// Awesome Screenshot https://www.diigo.com/awe/new-for-awesome-screensh...
// https:// chrome.google.com/webstore/detail/awesome-...
// chrome-extension://alelhddbbhepgpmgidjdcjakblofbmce/javascripts/presto/presto_content.js

Answer 1

Clarified the situation. Banal sniffer. Judging by the reviews on the webstore, users have already begun to massively demolish this extension.

Answer 2

Something about coupons, did you go to the addresses?
