As the single way I found to uninstall a webapp is to go to the about:apps page, I wanted to code the following:

 <p>To uninstall the webapp, please go to 
 <a href="about:apps">about:apps</a></p>

But, on Firefox v21 it does not open any page.

Then, I failed also using about:config.

 <a href="about:config">about:config</a>

Therefore I wonder whether it is possible to provide a hypertext link to the about:apps or about:config... What are your advices about this issue?

EDIT: document.location does not help

<html>
<body>
<script type="text/javascript">

//document.location = 'http://www.mozilla.org';
// -> OK 

  document.location = 'about:config';
  // -> Error: Access to 'about:config' from script denied
</script>

    have you tried `document.location` with Javascript? – Joum Jul 01 '13 at 14:17

    You probably found it already, but I also found https://groups.google.com/forum/#!topic/mozilla.dev.webapps/ySNNMUlE70c ... maybe it helps... – Joum Jul 02 '13 at 07:59
  • `document.location` does not work. Thanks @Joum for the link. I have found the same thread on mail-archive.com (http://www.mail-archive.com/dev-webapps@lists.mozilla.org/msg00578.html)... I will ask another question for that... Cheers – oHo Jul 02 '13 at 22:12

I think you are simple not allowed to insert a link to a local resource due to security issues.

  • I think so, but I have not found an official explanation of Mozilla... Please can you provide a reference for what you say? I would appreciate a lot ;-) Cheers – oHo Jul 02 '13 at 21:54

    If you do this for example: `click` and try it in the browser it comes up with an error: "Not allowed to load local resource: chrome://chrome/". Here http://stackoverflow.com/questions/13125616/link-to-chrome-chrome-extensions-from-extension-options-page is a post about how you might do it but when I tried it, it still didn't work. – putvande Jul 03 '13 at 08:53
