Hello Raiyad Raad, it is removed from Firefox 23 and above, you can do it only in about:config.
Tools-->>Options-->> Content-->> Disable java script-->> OK-->>Save Finally, Refresh your browser.
Close the Options window to save your changes. refresh your browser.
As ideato mentioned above, that option was removed starting with Firefox 23, so that won't be helpful. Ideato's method is correct/the only way to do that.

It can no longer be done globally from the User Interface. There are still a few other alternatives. Depending what you need to block it may be worth considering a script blocker something such as
- No Script http://noscript.net/
- Or search for something suitable in https://addons.mozilla.org/firefox/extensions/privacy-security/
Additionally if it is a specific website that you use often and wish to for instance block just parts of the media use the permissions for that page.
- Use the pageinfo page Firefox Page Info window
- Permissions Manager - Give certain websites the ability to store passwords, set cookies and more_how-do-i-manage-permissions-for-a-single-website
Maybe you are using an old version of Firefox if so it would be worth updating it
