About NoScript

My understanding of NoScript is that it allows the user to decide what scripts a website can execute. I want to learn more about the different capabilities (shown later) that can be toggled by NoScript.

Modes of NoScript

In the browser extension page, it shows that NoScript has 3 modes: Default, Trusted, Untrusted. All modes have the capacity to enable or disable the following capabilities:

  • script
  • object
  • media
  • frame
  • font
  • webgl
  • fetch
  • ping
  • noscript
  • unrestricted CSS
  • LAN
  • other

What I want to learn about these capabilities

I am already familiar with the following capabilities: noscript, LAN, webgl, font

These are the capabilities that I want to learn more about:

  • script
  • object
  • media
  • frame
  • fetch
  • ping
  • unrestricted CSS
  • other

I want to learn about the main function of each capability to further understand their significance.

What I've tried so far

None of these sections specifically talked about the significance and functions of each capability

  • searched stackexchange using the following queries:
    • noscript capabilities
    • firefox noscript extension capabilities
    • noscript extension capabilities
    • noscript extension modes
    • what does noscript do
    • what does the noscript extension do

None of these queries showed me results that talk about the different capabilities in NoScript

More Information

Browser: Firefox Browser 114.0.1 (64-bit)

NoScript version: 11.4.22

    Hello, please ask a specific question else this will get closed due to lack of focus. You ask not only about 8 different parts of software, but also split that into 3 parts.

  • Hello, I've updated my question to only focus on explaining the main function of the selected capabilities.

  • This is still a lot. Did you see forums.informaction.com/viewtopic.php?p=103816#p103816 also?

There's a list here about all these options:

  • script - JavaScript, e.g. <script> tags
  • object - plugin objects (usually Flash, Java applets, Silverlight, etc)
  • media - HTML5 audio/video
  • frame - subdocuments, e.g. <frame> and <iframe>
  • fetch - whether other sites can make XMLHttpRequest (sometimes abbreviated as "XHR") and Fetch request to this site
  • ping - destination of navigator.sendBeacon and hyperlink ping attribute
  • unrestricted CSS - when disabled for a site, NoScript mitigates pure-CSS exploits (e.g. CSS PP0) on pages served by that site
  • other - requests where Firefox cannot identify the request type (ref)
