How to run javascript in Mozilla URL bar?
I am using mozilla and trying to run this code on the url bar javascript:alert(document.cookie); but when I hit go, nothing happens. But in chromium, it alerts, so what is with the firefox? does firefox enters http by default. If this, then How do I prevent this?

Select Settings menu (3 horizontal lines icon in upper right corner) -> Web Developer -> Scratchpad.
Click the Run button on the Scratchpad toolbar to run your JavaScript code.
Firefox 56 and earlier
Open a new tab in Firefox and in the URL bar, and enter
about:blankto display a blank tab so that you can see what you are doing.From the Firefox menu select Tools -> Web Developer -> Web Console.
A new Web Console window will open. From the Web Console window click the JS button on the toolbar.
From the Web Console window click on the Scratchpad icon in the toolbar. The Scratchpad icon looks like a notepad.

For firefox android version, you can try this bookmarklet:
javascript:var a=prompt();var f=Function(a);f();
It will open a prompt box. Type your command in it (without "javascript:") and it will run.
