Open a tab in Mozilla Add On SDK

Question

I am developing a Mozilla Add on. I am trying to open a tab.

According to https://addons.mozilla.org/en-US/developers/docs/sdk/1.0/packages/addon-kit/docs/tabs.html it is done using

console.log("before tab");
var tabs = require("tabs");
tabs.open("http://www.example.com");

But it is not working on my case.

I am doing that in the content script. I have a page called popup.html and a content called popup_script.js.

The code is reached because the message is logged.

Any idea?

Content scripts don't have access to "advanced" APIs, they can merely communicate with the extension. So your content script should send a message to the extension and the extension should open the tab then. Like this:

self.port.emit("openTab", "http://www.example.com");

And in main.js:

panel.port.on("openTab", function(url)
{
  var tabs = require("tabs");
  tabs.open(url);
});
