title: Shiny dashboard rendering breaks in Firefox
body: <p>I have a R-shiny dashboard. It runs well as standalone program. However, as I open it in Firefox browser, it kind of breaks.</p>
  
  <p>Figure one shows how it looks as a standalone program. And figure two shows how it looks on Firefox.</p>
  
  <p>Here is the code that produces the part. </p>
  
  <pre><code> sidebar &lt;- dashboardSidebar(   
     sidebarMenu(
  
     menuItem("My Shiny",  tabName = "twebuddies_uhg", icon = icon("twitter-square"), 
                badgeLabel = "Info", badgeColor = "red" ),
  
   more menues
  </code></pre>
  
  <p>I appreciate your time and effort in helping with this. Thank you. </p>
