jQuery Auto Injector Addon/Extension for Firefox?

Question

I use a jQuery injector for chrome. This allows me to when I visit any website with the predefined script, it automatically injects. How ever, though I only have found a few and to my recolection, two that are reliable, I can't seem to find any for firefox. I will link the extensions of reference to what I use or have used. Additionally I am stating not just to inject but automatically inject even if you restart the browser. If it is possible to use a firefox extension to allow chrome extensions, please also inform me, thanks!

I currently use: Chrome Extension

I don't use: Chrome Extension

UPDATE: Workaround: My JsFiddle and GreaseMonkey

The Jquery Code:

/*
$('.guide').hide(0);
$('#appbar-guide-menu').hide(0);
$('#watch-discussion').hide(0).delay(0).show(0);
$('#guide-container').hide(0).delay(0).show(0);
$('#guide-main').hide(0).delay(0).show(0);
$('#watch7-sidebar').hide(0).delay(0).show(0);
*/

Answer 1

ok this is possible. for firefox-addon-sdk you use contentScriptFile like this:

var self = require('sdk/self');
var tabs = require("sdk/tabs");
tabs.open({
    url: self.data.url('ui/popup.html'),
    onOpen: function (tab) {
        var tabWorker = tab.attach({
            contentScriptFile: [
                self.data.url('ui/libs/jquery-1.8.3.min.js'),
                self.data.url('any-additonal-js-file-you-want-to-import.js')
            ]
        });
        tabWorker.port.emit('set-active-tab', tab.id);
    }
});

for bootstrap addon this example does what you need: https://gist.github.com/Noitidart/9406437
