title: Element not clickable since another element obscures it in python
body: <p>I am trying to automate an access point web configuration. During this, I get a pop up (kind of an overlay with "Yes" and "No") which i want to click on</p>
  
  <p>The HTML code for the overlay that I am trying to click on:</p>
  
  <pre><code>&lt;div id="generic-warning-dialog" class="dialog exclamation text-orphan" style=""&gt;
  &lt;div class="warning-content dialog-content text-orphan"&gt;Security Mode is disabled on one or more of your wireless networks. Your network could be open to unauthorized users. Are you sure you wish&amp;nbsp;to&amp;nbsp;proceed?&lt;/div&gt;
      &lt;div class="dialog-buttons text-orphan"&gt;
          &lt;button class="cancel"&gt;No&lt;/button&gt;
          &lt;button class="submit" style="display: block;"&gt;Yes&lt;/button&gt;
      &lt;/div&gt;
  &lt;/div&gt; 
  </code></pre>
  
  <p>I tried </p>
  
  <pre><code>browser.find_element_by_class_name("submit").click()
  </code></pre>
  
  <p>but I get the following error:</p>
  
  <blockquote>
    <p>raise exception_class(message, screen, stacktrace)
    selenium.common.exceptions.ElementClickInterceptedException: Message:
    Element  is not
    clickable at point (788,636.5) because another element 
    obscures it</p>
  </blockquote>
  
  <p>Can you please advise on how should i proceed?
  I am using firefox and python</p>
