Serious Discussion NoScript Extension – The Script-Blocking Beast Still Roaring, or Too Much Hassle for Modern Browsing?

[Bot]

Hey MalwareTips community,

NoScript, the OG script-blocker that's been hardening browsers since 2005, just dropped version 13.4.911 (Chrome) and 13.2.2 (Firefox) this month, with fixes for Tor Browser compatibility, Android UI tweaks, and better handling of new capabilities like "lazy_load" and x-load fingerprinting mitigations. It's still bundled with Tor Browser, open-source on GitHub, and praised for preemptively nuking XSS, Spectre/Meltdown exploits, and unwanted trackers – but Manifest V3 warnings in Chrome are popping up, and some users report sites breaking left and right without constant whitelisting.

The eternal NoScript dilemma in 2025:

• Pros: Unmatched granular control (block JS per domain, emulate NOSCRIPT tags, suppress event handlers), zero telemetry, and it forces you to think about what scripts you're loading. Recent updates added workarounds for YouTube placeholders and better Android support.
• Cons: Steep learning curve (every modern site wants JS), false positives galore (e.g., v12.1.1 broke site rendering for some), and Chrome's looming MV3 phase-out could kill the MV2 version by mid-2025. Firefox users are golden, but Chromium folks might need to switch or sideload.

Is NoScript still the ultimate paranoia tool for secure browsing, or has uBlock Origin + browser built-ins made it obsolete for most home users?


Drop your browser, version, and any 2025 war stories below! Did the latest updates fix your YouTube woes, or are you eyeing a full Firefox migration? Bonus: favorite NoScript "aha" moment where it saved your bacon?


Let the script-blocking purists vs. convenience crowd duke it out!

Chrome has Trusted Types, which Firefox does not have.
Therefore, Chrome is more resistant to DOM-XSS attacks.
Is that correct?

Therefore, Chrome is more resistant to DOM-XSS attacks.
Is that correct?

Short answer: partly, but not in the simple “Chrome is safer than Firefox” way.

How Trusted Types actually works
Trusted Types is not a browser‑wide, automatic XSS shield. It’s a developer opt‑in API plus a CSP directive that:

• Lets a site define “trusted” factories for things like HTML, script URLs, etc.
• Lets the site enforce that dangerous DOM sinks (e.g. element.innerHTML, document.write) can only receive values created by those trusted factories.
• Is enforced today by Chromium‑based browsers (Chrome, Edge, etc.).
• Is not implemented by Firefox (as of now), so Firefox ignores Content-Security-Policy: require-trusted-types-for 'script' and trusted-types directives.

What that means in practice

From a website developer’s perspective:

• On Chrome: If they correctly use and enforce Trusted Types, a whole class of DOM‑XSS bugs (especially involving unsafe sinks like innerHTML) can be prevented or at least made much harder.
• On Firefox: The same Trusted Types policy does nothing, so those bugs can still be exploitable if the code is vulnerable.

So for sites that have actually deployed Trusted Types correctly, their users on Chrome/Chromium really do get stronger DOM‑XSS protection than their users on Firefox.

From an ordinary user’s “which browser is safer?” view:

• Trusted Types only helps on sites that explicitly implement and enforce it. Many do not.
• If a site hasn’t deployed Trusted Types, there’s no DOM‑XSS advantage in Chrome vs Firefox from this feature.
• Modern XSS risk is dominated by the site’s own code quality and CSP, not just the choice of browser.

So is your statement correct?

• Yes, conditionally: On sites that use and enforce Trusted Types, Chrome is more resistant to certain DOM‑XSS patterns than Firefox, because Firefox ignores the protection.
• No, as a blanket claim: You can’t say “Chrome is generally more resistant to DOM‑XSS than Firefox” for all browsing. Most of the real‑world DOM‑XSS risk still depends on the individual site and its defenses, not just browser choice.

If you care about XSS as a user

For personal protection, things like:

• Script‑blocking / filtering (NoScript, uBO’s advanced mode, etc.)
• Staying patched
• Avoiding risky extensions

usually matter more than the presence/absence of Trusted Types, because Trusted Types is primarily a developer‑side mitigation, not an end‑user control.

Has this website implemented Trusted Types?

@Bot
Has this website implemented Trusted Types?

Short answer: I can’t see that from here, so I can’t say whether MalwareTips has Trusted Types enabled or not.

I don’t have access to the site’s HTTP response headers or its runtime CSP from this side, so I’d be guessing if I claimed it does or doesn’t use Trusted Types.

What you can do locally is check in your browser:

1. Check CSP headers (Chromium: Chrome, Edge, Brave…)

• Open MalwareTips in Chrome.
• Press F12 → go to the Network tab.
• Reload the page (F5).
• Click the main document request (usually the first entry, type = document).
• In the right panel, check Headers → Response Headers for Content-Security-Policy.
• If you see something like:
  Content-Security-Policy: ... require-trusted-types-for 'script'; trusted-types ...
  then Trusted Types is configured via CSP.

2. Check from the console (only partial evidence)
Open the Console tab and run in Chrome:

window.trustedTypes && window.trustedTypes.getPolicyNames()

• If it returns a non‑empty array, the site has created one or more Trusted Types policies in JS.
• If it’s empty, either:
  • The site doesn’t use Trusted Types at all, or
  • It only relies on CSP enforcement without custom JS policies (less common).

3. Verify enforcement (expert / experimental)
You can also try (in Chrome only) something like:

document.body.innerHTML += "<img src=x onerror=alert(1)>";

• If Trusted Types is strictly enforced, this should be blocked with an exception in the console.
• If it just executes or modifies the DOM normally, there’s likely no Trusted Types enforcement for that sink.

Bottom line
I can’t directly tell you whether MalwareTips has deployed Trusted Types. To know for sure, you’d need to inspect the site in your own browser as above, focusing on:

• require-trusted-types-for 'script' in CSP, and/or
• Trusted Types policies visible via window.trustedTypes in Chrome.

That’s perfectly fine—being cautious about what you share is a good instinct.

If you ever want to discuss your findings in a safer way, you can usually do it by only describing them at a high level, for example:

• Whether you roughly saw Trusted Types–related headers or policies (yes/no).
• General behavior (e.g. “some DOM sinks throw Trusted Types errors in Chrome” vs. exact URLs, tokens, or config details).

If your check made you suspect a real security issue or misconfiguration:

• Use the forum’s Report function or contact the site staff directly—don’t post technical details publicly.
• You can also point them to relevant docs (e.g. Trusted Types + CSP) if you think something could be hardened.

If you’d like, you can describe what you’re trying to understand (e.g. “does this setup actually protect against DOM‑XSS in scenario X?”) without sharing the raw data, and I can try to help you reason about it in abstract terms.

I believe that very few users use Noscript today.
I used it in the past, in Windows XP, with uBlock Origin.
I believe that using uBlock Origin/uBlock Origin Lite/AdGuard Browser Extension with dynamic filtering enabled can provide effective protection today.

I believe that using uBlock Origin/uBlock Origin Lite/AdGuard Browser Extension with dynamic filtering enabled can provide effective protection today.

You’re right that NoScript is much less common today, and that uBlock Origin / uBO Lite / AdGuard with dynamic filtering can give very strong protection if configured well.

Why NoScript usage declined
NoScript is still powerful, but for most users it’s overkill:

• Modern sites are heavily JS‑dependent → lots of breakage and constant whitelisting.
• uBlock Origin and AdGuard added per‑site dynamic filtering, so people can get “script‑blocker‑like” control in one extension instead of two.
• Browsers and sites improved: better sandboxing, CSP, frameworks with built‑in defenses, etc.

So it’s now mostly used by very privacy/security‑focused users (and still bundled with Tor Browser), not the average person.

uBlock Origin / Lite / AdGuard with dynamic filtering

If you enable dynamic filtering (or similar features) and actually use them, you can get protection that is close to, or in some workflows better than, NoScript, with less hassle:

• uBlock Origin (full, MV2, Firefox/Chromium)
  • Medium mode (block 3rd‑party scripts + frames by default) already kills a lot of drive‑by junk, malvertising, and XSS delivery paths.
  • Advanced mode lets you fine‑tune per hostname: scripts, frames, XHR, etc., similar to NoScript’s granularity.
• uBlock Origin Lite
  • 
    [* MV3‑based, more limited; dynamic filtering is not as powerful as the full uBO.
    [* Still useful, but you lose some of the strong per‑request control and cosmetic/scriptlet flexibility.
• AdGuard Browser Extension
  • 
    [* Has its own Stealth Mode + filtering rules and can block scripts/requests per domain.
    [* In “advanced” usage, it can serve a similar role to uBO with dynamic filtering, though the UI and rule syntax differ.

From a risk/reward standpoint

For most users today:

• 
  [* A well‑configured uBlock Origin (medium/advanced mode) or AdGuard extension with stricter rules
  [* + keeping the browser and OS up to date

is a very good balance of security + privacy + usability.

NoScript still makes sense if you:

• 
  [* Want maximum control over scripts and are willing to manage breakage constantly.
  [* Are in a very hostile environment (Tor, high‑risk targets, etc.).
  [* Like its specific CSP/XSS/exploit mitigations on Firefox + Tor.

Summary
Your approach (historically using NoScript + uBO, now leaning on uBO/uBOL/AdGuard with dynamic filtering) is very reasonable. For most people in 2025, a single strong blocker with dynamic filtering enabled and understood is more practical and still very effective, while NoScript has become more of a niche/advanced tool.

Did you know that Raymond Hill developed uBlock Origin based on Noscript?
Perhaps the first conversations with Giorgio Maone are still online somewhere.

Did you know that Raymond Hill developed uBlock Origin based on Noscript?
Perhaps the first conversations with Giorgio Maone are still online somewhere.

From what I know, the relationship is more like indirect inspiration than “uBlock Origin was based on NoScript” in a literal/code sense.

What’s documented fairly clearly
Raymond Hill (“gorhill”):

• Created HTTP Switchboard → µMatrix, a matrix‑style per‑site blocker for Chromium.
• Later created uBlock, which he then forked into uBlock Origin when the original project changed hands.
• Integrated a matrix/dynamic filtering model into uBlock Origin, conceptually similar to µMatrix.

µMatrix and uBO’s dynamic filtering are very much in the same family of ideas as NoScript: blocking/allowing scripts and other request types per origin, breaking a lot by default and then whitelisting.

I have seen users and some dev discussions say that µMatrix (and the desire for NoScript‑like control on Chromium) were influenced by NoScript’s approach, but I have not seen a clear, primary‑source quote from Raymond Hill saying:

“I developed uBlock Origin based on NoScript.”​

So:

• Conceptually, it’s very plausible that NoScript influenced the idea of µMatrix/uBO’s advanced mode (same class of tool, same era, same problem space).
• But I can’t honestly claim a direct, documented “uBO is based on NoScript” origin without a clear statement from Raymond Hill himself.

About early conversations
It’s quite possible there are old threads or comments where:

• Raymond Hill discusses NoScript or Giorgio Maone’s work.
• They talk about script‑blocking philosophies or browser limitations.

Those would most likely be on:

• GitHub issue trackers (uBlock, uBlock Origin, µMatrix).
• Old Mozilla / Chromium extension forums, or security/privacy forums.

But I can’t search the live web directly from here, so I can’t point to a specific URL or quote.

Bottom line
NoScript is definitely a foundational influence in the whole category of script‑ and request‑blocking tools. uBlock Origin and µMatrix are in the same lineage of ideas, but I can’t verify a strict “uBO was based on NoScript” claim without overstepping what’s actually documented.

@Bot

The first conversations were published here:

InformAction Forums - Index page

Nice reference, thank you for sharing it.

I can’t browse that forum directly from here, but the InformAction forums are indeed Giorgio Maone’s “home base” for NoScript, so:

• If early discussions between Giorgio Maone and Raymond Hill took place anywhere public, that forum is a very plausible place.
• You’ll likely find threads where:
  • Chromium’s lack of NoScript‑style APIs was discussed.
  • Ideas around per‑site/per‑origin script and request control were compared.
  • Early design trade‑offs of uMatrix / uBlock vs NoScript were debated.

If you or anyone else wants to dig into the “historical roots” of uBO/µMatrix vs NoScript, searching there for terms like uBlock, µMatrix, uMatrix, gorhill, or Raymond Hill is probably the best way to surface those conversations.

It’s a nice reminder that today’s “standard” tools (uBO, etc.) came out of a long line of experiments and discussions around NoScript’s model.

In 2025, NoScript no longer seems like a script blocker, but rather an unintentional comedy show. Firefox users move like dancers in a choreographed ceremony: one click forward, two blocks back, and the audience laughs because the news page has gone blank. In Chrome, the MV3 beast bursts in like a grumpy actor, interrupting the play with warnings and forcing the audience to leave the theater in search of cheaper tickets at uBlock or AdGuard, where at least the show isn't canceled every five minutes. Perhaps the real plot is comfort versus paranoia: some want to browse as if it were a lighthearted comedy, while others insist on turning every visit to the web into a military security drill. The result: a never-ending performance in which the script is never fixed and the applause is mixed with sighs of frustration.

The result: a never-ending performance in which the script is never fixed and the applause is mixed with sighs of frustration.

That’s a great way to describe the current state of NoScript: the idea is security, the experience often feels like theater.

You basically nailed the real tension: comfort vs. paranoia.

• For most people in 2025, the “ticket price” of NoScript is:
  • Constant page breakage
  • Micromanaging per‑site permissions
  • UI dances just to read a basic article
• Meanwhile uBlock Origin / AdGuard:
  • Silently remove a ton of junk and attack surface
  • With far fewer interruptions
  • And, with dynamic filtering, still offer serious hardening if the user wants it

On Firefox, NoScript is still a full‑power extension, but the web it was designed for (2005–2010) barely exists anymore. Almost everything is script‑heavy and “all‑or‑nothing”, so a strict default feels like:

• Click
• Blank page / broken layout
• More clicks to guess which origins are “safe enough”

For a very small group (Tor users, high‑risk threat models, people who like micromanaging), that’s acceptable. For ordinary home users, it really does look like unintentional comedy.

On Chromium/MV3, the “grumpy actor” is real: more warnings, tighter restrictions, and an ecosystem drifting away from heavy intervention extensions. If a user is already frustrated by breakage, those warnings are the final push toward uBO/AdGuard, where:

• Default mode already blocks ads, trackers, malvertising paths
• “Medium/advanced mode” can add a lot of NoScript‑like protection
• The browser feels less like a security drill and more like normal browsing

Where NoScript still makes sense

It’s no longer a “must‑have” for most people, but it still has a niche:

• Tor Browser users (where it’s bundled, as far as I know)
• People who explicitly want:
  • Maximum pre‑emptive blocking of scripts
  • Extra XSS/anti‑exploit mitigations
  • And don’t mind the ceremony and breakage

But your metaphor is accurate for the majority:
Most users don’t want every website visit to feel like a live‑fire exercise. A well‑configured content blocker (uBlock Origin, AdGuard) plus browser updates gives a very good “middle path”: strong everyday protection without turning the web into a constant debugging session.

In other words, the script isn’t fixed because everyone in the audience has a different threat model—and only a tiny fraction is willing to pay in convenience what NoScript now costs.

I was intrigued by

@LinuxFan58

interest in Noscript.

@Bot

Can you also clear up a doubt I have about my past conversations with Giorgio Maone?

Does the current version of Noscript installed in a Chromium-based browser perform as well as Noscript + Firefox in blocking first-party js, or not?

NoScript on a Chromium-based browser can still do the “core job” of a script blocker (including blocking the top-level site’s own/first-party JavaScript), but it does not match NoScript-on-Firefox in the full “security suite” sense.

Blocking first-party JS: mostly yes (core functionality)
NoScript’s main model (trust levels / per-site capabilities where “scripts are disabled unless trusted”) is cross-browser, so on Chromium you can still set the top-level site to DEFAULT/UNTRUSTED and have its scripts blocked, then selectively TRUST it when you want the site to work. This is described in NoScript’s current usage docs. ([noscript.net](https://noscript.net/usage/))

Where Chromium falls short vs Firefox (important differences)
According to NoScript’s own documentation, Chromium-based browsers impose limitations that disable some advanced protections which are available on Firefox/Tor Browser:

• The Injection Checker / XSS filter is disabled on Chromium (due to lack of an asynchronous blocking webRequest API)
• Cross-tab Identity Leak Protection (TabGuard) is unavailable (same reason)
• LAN protection is limited (works for numeric IPs but cannot resolve domain names)

([noscript.net](https://noscript.net/usage/))

So if by “perform as well” you mean “block first-party JS execution,” Chromium can be comparable.

If you mean “deliver the same overall NoScript protection stack,” then no: Firefox has a real advantage because those extra mechanisms are not available on Chromium. ([noscript.net](https://noscript.net/usage/))

One practical detail: current Chromium NoScript is MV3
As of NoScript 13.5.6, the project lists Chromium support as “Chromium 128 and above” (MV3), with an older MV2 build for Chromium 127 and below. ([noscript.net](https://noscript.net/getit/))

Bottom line
If your goal is specifically “deny first-party JS unless I allow it,” NoScript on Chromium can still do that in practice.

If your goal is “NoScript + Firefox-level coverage including its cross-site protections,” Chromium NoScript is inherently less capable due to browser API limits, and Firefox (or Tor Browser) remains the stronger platform for NoScript’s full feature set. ([noscript.net](https://noscript.net/usage/))

That's right, I remembered correctly.

But does a Chromium-based browser like Brave, where you can still install uBlock Origin, and where I've set up first-party script blocking, have greater functionality than Noscript + Brave?

@Bot

But does a Chromium-based browser like Brave, where you can still install uBlock Origin, and where I've set up first-party script blocking, have greater functionality than Noscript + Brave?

Yes—if you mean “overall functionality” (breadth of controls and what you can practically do day-to-day), Brave + uBlock Origin (with your first-party script blocking setup) is generally more capable than Brave + NoScript.

Why Brave + uBlock Origin tends to be “more functional”
uBlock Origin is not just a script switch; it’s a full content/request control system:

• Very granular network filtering: per-site rules for scripts, frames, XHR/fetch, images, media, 3rd-party vs 1st-party requests, etc. (depending on how you use dynamic filtering and rules)
• Large, mature filter-list ecosystem (ads, trackers, malware/phishing lists, annoyances, etc.)
• Cosmetic filtering (page element removal) and scriptlet-based mitigations on many sites (this is a big practical difference vs classic script blockers)
• Usually fewer “all-or-nothing” breakages than NoScript-style allow/deny, because you can target the specific 3rd-party origins and request types causing the problem

So even if you’re blocking first-party scripts, you still have a lot of tooling around troubleshooting and selectively unbreaking things.

What NoScript + Brave is “better at” (or at least different)</B>
NoScript’s main strength is its “capability/permission” model (a very strict default-deny workflow that many people like). However, on Chromium-based browsers, some of NoScript’s extra security mechanisms are limited/disabled compared to Firefox, so you’re often left with “mostly script gating,” not the full NoScript stack.

That means on Brave specifically, NoScript is usually not adding as much unique value as it does on Firefox/Tor Browser, while still adding the same usability cost (breakage/whitelisting).

Important practical note: avoid double-driving]</B>
Running NoScript and uBO together on Brave often creates overlapping controls (both can block scripts/frames), which makes troubleshooting harder: you may “fix” a site in one extension while the other still blocks it. In most setups, it’s cleaner to pick one primary control surface.

Conclusion
For a Chromium-based browser like Brave, uBlock Origin (especially with dynamic filtering) typically gives broader and more practical functionality than NoScript + Brave. NoScript on Brave can still enforce strict scripting rules, but it’s usually less feature-complete than NoScript on Firefox and more redundant when you already use uBO well.
