Can somebody provide an example of content script which executes only on example.com pages? Just like in Chrome extensions.
I can't figure out with this SDKs and weird things. In Chrome it's easy.
Please, no Firefox XUL interface.
I mean, it will be very good to see whole extension example, not just code.

I have built a Chrome App which needs to load some websites inside its own window.
The purpose is to display full-screen contents on TVs using Google Chromeboxes in Kiosk mode.
I can't use iframes as the content I must load doesn't allow it.
My researches led me to some code like :
chrome.browserAction.onClicked.addListener(function(tab) {
chrome.tabs.create({'url': event.target.href})
})
This seems to open a new tab on the browser running the extension, but not in the extension window.
The vision I have about chrome apps may be confused as it's the first I'm developing, please don't hesitate to tell me the basics I would not have heard of
You need to use the <webview> tag, available in Chrome Apps, to embed external content.
This does not trigger anti-framing protection, since from the point of view of web security each <webview> is a top-level browsing context.
Note the limitations of <webview>: some web features like message boxes or permission requests have to be implemented by you.
As an example of webview usage, see the Browser sample app.
I have written a Chrome extension and a Chrome packaged app. The extension uses the chrome.webRequest.onAuthRequired extension API. I've installed this extension in Chrome.
When I create a window in the Chrome App with chrome.app.window.create, the extension is not active.
How can I launch a window from my Chrome App in which the extension is active?
Ideally, I'd like to be able to use the chrome.webRequest API in my app, but I believe that is not possible.
Also, I understand that communication between a Chrome App and Chrome Extension is possible, (as in this this question), but I really hope I won't have to use message passing, and I don't know if that would even work as I'm not sure I could get the app to recognize when authorization was being requested.
Any thoughts would be appreciated. Thanks!
I use Firebug to do most of my web debugging. In one of the web applications I'm working on, the application breaks when Firebug is enabled; it seems that some JS resources (mainly jQuery) aren't being loaded. When I disable Firebug, the site works great. Any ideas on how Firebug might be interfering with how the site runs, and what can be done to fix it?
I designed a web page which contains some javascripts, but when I'm running the page in certain browsers like internet explorer my scripts get blocke and the browsers asks for manual enabling of the script in that browser
I need java script or jquery code for enabling script run in any browser automatically. Can anyone help me please?
Thank you
It is impossible for a website to turn on JavaScript if it is disabled in the browser.
Design your site with progressive enhancement and unobtrusive JavaScript in mind.
If, by "certain browsers like internet explorer", you mean "Internet Explorer will not run my code" (as opposed to "Browsers wil JS turned off will not run my code") then you may just need to learn how to write cross-browser compatible code.
Without a specific example of code that does not work (along with the specific error messages you receive), that topic is too broad to cover on StackOverflow.
Sounds like you are running the website locally, ie opening the file not serving it from a web server. Try running a local web server or hosting your site on a free online service and as long as the browser doesn't have JavaScript disabled the messages shouldn't show up.
I'm trying to use Firebug to debug a JavaScript file in an extension I've added to Fx 4.
Can anyone tell me how to do it? I can only see website scripts.
Use Chromebug it's firebug for extension development, witch will give you the full ability to inspect debug firefox it self and all firefox extension as if it's a webpage :)
1- install the latest version from here: http://getfirebug.com/releases/chromebug/
2- Winkey+R to open run then type firefox.exe -chromebug this will run firefox with chromebug
3- for more information visit http://getfirebug.com/wiki/index.php/Chromebug
Please see MDN - Building An Extension - Debugging Extensions, which shows what tools Firefox provides you with to natively debug extension, also take a look at Dive Into Greasemonkey - Debugging User Scripts (PDF, p.13) which is aimed more specifically at your request.
Other than that, see How to debug a Greasemonkey script with the Firebug extension?
On Firefox 19 or later, it's possible to use the built-in JS debugger on the browser itself. Go to about:config and set the following two prefs:
devtools.chrome.enabled: true
devtools.debugger.remote-enabled: true
After you restart the browser, you can access the Browser Debugger through Tools > Web Developer > Browser Toolbox.
(note that you must accept the incoming connection)

In the bottom right hand corner there should be a little Firebug icon. Single or double click to open then you see some tabs at the top. Click the "Console" tab for real time debugging, or the "SCript" tab to view the scripts that have been loaded. Note, you can also load CSS and HTML through Firebug, use the "Viewer" icon to view HTML code on the page in real time.
