title: How to avoid a security warning in icedtea-web
body: <p>There is a site that I visit often, which has some buttons programmed in java (for no reason). There is a missing permission attribute, and so each time I enter the site, I receive this message
  <a href="https://i.stack.imgur.com/ZQxcn.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ZQxcn.png" alt="enter image description here"></a></p>
  
  <p>In fact, I receive one of those for each button. I am using icedtea-web 1.6.2 on <strong>Arch Linux</strong>. I tried to add an exception by writing the URL of this page in the file <code>$HOME/.java/deployment/security/exception.sites</code>, but it did not work, I still receive the message.</p>
  
  <p>How can I do to stop receiving those messages? I use Firefox 50.1.0.</p>
