Answer 1

This type of error is usually caused by an updated DOM. I would suggest that you on all pages that contain javascript/ajax calls actually wait for those calls to finish before interacting with the site. I generally perform this wait just after the page has loaded, and when performing some kind of action that triggers javascript/ajax calls and/or updates to the DOM. In practice, this means running the below function after the page has loaded (or has been interacted with), and after that find the element you want to interact with.

public void WaitForJqueryAjax() {
        int delay = MaxdelaySeconds;
        while(delay > 0) {
            Thread.Sleep(1000);
            var jquery = (bool)(this.driver as IJavaScriptExecutor)
                .ExecuteScript("return window.jQuery == undefined");
            if(jquery) {
                break;
            }
            var ajaxIsComplete = (bool)(this.driver as IJavaScriptExecutor)
                .ExecuteScript("return window.jQuery.active == 0");
            if(ajaxIsComplete) {
                break;
            }
            delay--;
        }
    }
