I am trying to install App using App Manager in Firefox OS device. But my problem is I am unable to push any of the apps which are published on MarketPlace. It show that 

The webapp manifest isn't a valid JSON file: SyntaxError: JSON.parse:
unexpected character at line 1 column 1 of the JSON data at: 
https://marketplace.firefox.com/app/pacman-canvas can't be opened

So can anyone suggest some way to push the app to my device using App Manager only?

It's pretty easy. On the Marketplace page (in Firefox desktop) open the marketplace page for the app. Then open Devtools and select the Debugger. In the debugger, break in file iframe-installer.html, on this line:

installPackage(e);

Now click the 'Free' button, the debugger will break on this line. In the console you now type:

e.data.data.product.manifest_url

This will give you a URL. If the URL is located at someone else's webserver (like Pacman), e.g. http://pacman.platzh1rsch.ch/pacman-canvas.webapp, you can (in the App Manager) click 'Add hosted app' and paste the URL. However you will need internet on the phone the first time you use the app (because its hosted app).

If the URL is a Mozilla URL (https://marketplace.firefox.com/app/etc.), you can open the link in your browser. Open the file. You now have a JSON file in which you need to look for the package_path key. F.e. for Recorder it's 

"package_path": "https://marketplace.firefox.com/downloads/file/258677/recorder-1.1.zip"

You can now download this ZIP file, unzip it in a folder, and add the folder as a Packaged app.
