How to call content_script from main.js

[Kwstas Na]

Hello.

I have read the tutorial and some of the "how to use content-script.js"

But here is my problem.

I 've made one chrome extension which works perfect.

And i want to make it also to firefox.

So how can i write the main.js

to be like the chrome background.js??

chrome.browserAction.onClicked.addListener(function(tab) {

    chrome.tabs.executeScript(tab.id, {

allFrames: true,

        file: "content_script.js"

    }, function() {

        if (chrome.runtime.lastError) {

            console.error(chrome.runtime.lastError.message);

        }

    });

});

And also how to load on the main.js the .png addon pictures?!

Fyi. isn't there any chrome to firefox extension converter? :/

Thanks a lot for your time watching this.
