title: HTML input value not refreshing properly in Firefox after modified by JS
body: <p>I have an <code>&lt;input&gt;</code> element which receives a default value (i.e. <code>180</code>) on page load.</p>
  
  <pre><code>&lt;label id="tl" class="secondary_text" title="title"&gt;Time limit [s]&lt;/label&gt;
          &lt;p&gt;
            &lt;input id="spinner-timelimit" class="spinner-ten" name="spinner" value="180"&gt;
          &lt;/p&gt;
  </code></pre>
  
  <p>If I modify the original value (manually or using a jQueryUI spinner), the new value is stored, even after I refresh the page using <code>F5</code>.
  I'd like for the default HTML value to be reapplied after reload of the page, not the one that was input by a user.</p>
  
  <p>I don't believe this is an ordinary cache problem, as I have disabled cache in the Firefox console, under Network tab.</p>
  
  <p>I tried reproducing the situation in a <a href="https://jsfiddle.net/sc28/7w45xu3e/2/" rel="nofollow noreferrer">JSFiddle</a>, but there the refresh using Run correctly restores the default value, so doesn't reproduce the problem.</p>
  
  <p>Note that this only happens in Firefox, not in Chrome. Can anything be done to force the HTML refresh in Firefox?</p>
