Google Minus One geliştiren: Claire Rosenthal

Removes the 'Upgrade' advertisement on Google online products, including Docs, Mail, Drive, etc.
Around 25 lines of actual code. Nothing fancy. I'm going to post the code here in case you want to look at it:

function waitForElm(selector) {
return new Promise((resolve) => {
if (document.querySelector(selector)) {
return resolve(document.querySelector(selector));
}

const observer = new MutationObserver((mutations) => {
if (document.querySelector(selector)) {
observer.disconnect();
resolve(document.querySelector(selector));
}
});

// If you get "parameter 1 is not of type 'Node'" error, see https://stackoverflow.com/a/77855838/492336
observer.observe(document.body, {
childList: true,
subtree: true,
});
});
}

// This is where the waiting for and selection of the html element starts.
// Here is where the different selection ids come from:
// .s1rbBe is the upgrade selector for Gmail
// .appsElementsWorkspaceRecommendationContentButtonFull is the upgrade button selector for Google Workspace (Docs, Sheets, etc.)
// .wKxlIc is the upgrade button selector for Google Calendar
// .Iu19ad-OkO9ve-yp5uJf-j is the upgrade button selector for Google Drive
waitForElm(
".s1rbBe,.appsElementsWorkspaceRecommendationContentButtonFull,.wKxlIc,.Iu19ad-OkO9ve-yp5uJf-j",
).then((elm) => {
elm.remove();
});
