How to enable/disable JavaScript in Firefox-23.
I did check the release notes of Firefox-23 it says, "Enable JavaScript" preference checkbox has been removed and user-set values will be reset to the default.
I have been using the enable/disable JavaScript feature to check if my developing website behaves as expected without JS. How do I disable JavaScript now. As of now am using web developer add-on, but, I don't want to use it as it fills most of my webpage. Looking for an alternative.
Why this feature was removed.?

JavaScript is now disabled in your Firefox browser. To re-enable it at any time, change the value of javascript. enabled to true.
You can still access it from about:config or by installing an add-on. '''about:config''' # In the address bar, type "about:config" (with no quotes), and press Enter. # Click "I'll be careful, I promise" # In the search bar, search for "javascript. enabled" (with no quotes).
From Firefox 24 on, web developers have the option to turn off JavaScript temporarily. Open the Web Console via the menu or the Ctrl-Shift-K shortcut and click on the preferences icon there. Here you find disable JavaScript under advanced settings. This disables it only for the current session though.
https://developer.mozilla.org/en-US/docs/Mozilla/Firefox/Releases/23 says:
You may still disable JavaScript by double clicking the "javascript.enabled" option in about:config.
Other choices are the noscript plugin, or next generation devtools.

If you type about:config in your URL bar, and search for 'javascript' there is an entry javascript.enabled which you can set to false or true.
