Flush Custom Search

At the time of writing, this “feature” cannot be disabled without a dedicated chrome extension¹. And of course removing each item one by one is unreasonable.

Hence the following JS snippet iterate over each item in the list and clicks the delete button.

Usage#

1. Go to the search engine settings chrome://settings/searchEngines.
2. Open the Developer Tools by clicking F12 or CTRL+SHIFT+I.
3. Copy the script below and paste it in the Javascript console tab.
4. Fire Away.

Snippet#

A slight delay has been added between clicks since after each action the browser takes a moment to render the view. feel free to adjust the sleep at line 16 as you see fit.

const otherEngines = document.querySelector("body > settings-ui")
                    .shadowRoot.querySelector("#main")
                    .shadowRoot.querySelector("settings-basic-page")
                    .shadowRoot.querySelector("#basicPage > settings-section.expanded > settings-search-page")
                    .shadowRoot.querySelector("#pages > settings-subpage > settings-search-engines-page")
                    .shadowRoot.querySelector("#otherEngines").shadowRoot

let n = otherEngines.querySelector('iron-list').childElementCount - 1;
let rmbtn = otherEngines.querySelector('#frb0')
                        .shadowRoot.querySelector('#delete')

const sleep = (ms) => new Promise(resolve => setTimeout(resolve, ms));

while(n--) {
	rmbtn.click();
	await sleep(2000);
}
