Override javascript file with chrome extension - google-chrome-extension

I know I can use the sources tab to override a javascript file with a local version, but how do I do it through a chrome extension. I am fairly new to development of chrome extensions so any help is appreciated.

Where can I see if my chrome extension is enabled without opening the browser?

I have an extension loaded into my Google Chrome and I’d like to be able to tell whether it is enabled or not without having to open Chrome and go to the extensions page. Is there a way to do that?
If that matters, the extension is located in the appdata/local/Google/chrome/default/extensions folder.

How protect chrome extension of reupload

Everybody can download chrome extension, edit and reupload, how i can protect my chrome extension and what i need to do if i see someone reupload my chrome extension?
You can't bulletproof-protect it. The only thing you can reasonably guarantee to be unique is the extension ID for published items - but any checks you would do against it can be circumvented.
It's not a technical problem. It's a social/legal problem.
If you see someone doing it, you should use the Report Abuse function of the Web Store.
What other does is to load the "actual" code of their extension remotely (via CDN)
The code that is packaged with chrome extension just act as loader or their "real" extension code.
See Streak's InboxSDK (sdk to build chrome extensions for gmail). It uses the same concept. https://www.inboxsdk.com/docs/

Postman application- extension from chrome is written in which language?

This could be layman question. I use the postman application which i got from the chrome extension. It was soo good. I really want to know in which language it is written? Is it written completely in javascript and packaged using some tools like cardova? Or any native language is used?
It is a "chrome app" written in HTML5, CSS, and JavaScript.

Interacting with Chrome extension using watir-webdriver

I am able to launch Chrome browser with extension in the browser. But I am not able to interact with the extension.
When I launch Chrome browser manually, I go to chrome://extensions and configure command for that extension and set short cut like "Alt+H" to launch the extension from short cut and after hitting Alt+H the extension gets invoked.
But when I launch chrome browser with extension using watir webdriver, the configure command setting for that extension is not set. After I set that manually again to "Alt+H" and try to invoke the extension on the browser which is launched using watir-webdriver, I don't see extension getting invoked.
Please let me know how can I interact with the chrome extension using watir-webdriver.
I do not think watir can interact with the extensions. It can only interact with the page. But, I could be wrong. I had moderate success with Sikuli when I needed to do something like that.

Example of Chrome and Firefox Extensions sharing the same code?

I am looking for a sample project that would compile a chrome and firefox extension that would run some JavaScript code after a page is loaded.
I already wrote a Chrome extension that does this, but I am looking for something cross-browser, that would allow me to build the same extension for Chrome and Firefox.
If this would also allow me to publish the extensions it would be great.
You may refer this link http://www.extensionfactory.com/labs/conversion/
Here you can get firefox extension by submitting chrome extension.
With the Crossrider's framework you can build a cross-browser extension using only one code base that will work on Chrome, Firefox and also Internet Explorer and Safari.
So, with only using javascript single code base and the Crossrider API you can easily build your first cross-browser extension in no time.
