Previously, Firefox had discarded the
HTMLElement.click method triggered on an element that wasn’t part of a
document. On Firefox 74 and later, such method calls will work and the corresponding
click event will be fired on that element. Since the new behaviour mostly aligns with other browsers, it’s unlikely to cause site compatibility issues. However, if a site is using a user-agent sniffing to run code specific to Firefox that assumes the
click event will not be fired, this change could be a potential problem.
const $input = document.createElement('input'); // This `click` event will be logged from now on $input.addEventListener('click', event => console.log(event)); // Here the `<input>` is not yet added to the `document` $input.click();
