boolean. If true, this makes the reload ignore the browser cache (as if the user had pressed Shift+Ctrl+R).

userAgent Optional

string. Set a custom user agent for the page. The string supplied here will be sent in the browser's User-Agent header, and will be returned by calls to navigator.userAgent made by scripts running in the page.

injectedScript Optional

string. Inject the given JavaScript expression into all frames in the page, before any other scripts.

Browser compatibility

BCD tables only load in the browser

reloadButton.addEventListener("click", () => {
    userAgent: "Not a real UA"
