uMatrix: een contextafhankelijke en matrix-gebaseerde firewall, met vele functies ter verbetering van uw privacy.
*Voor gevorderde gebruikers.*
uMatrix geeft volledige controle over welke verbindingen uw browser mag maken, welk type gegevens de browser mag downloaden, en wat erin mag worden uitgevoerd. Niemand anders beslist het: het is uw keuze. U hebt de volledige controle over uw privacy.
Direct na installatie werkt uMatrix in de modus alles-blokkeren/bij-uitzondering-blokkeren, wat inhoudt dat websites die scripts van derden nodig hebben waarschijnlijk niet goed worden weergegeven. Met twee muisklikken kan uMatrix worden ingesteld om in de modus alles-toestaan/bij-uitzondering-blokkeren te werken, waarmee websites doorgaans wel goed worden weergegeven. Zie https://github.com/gorhill/httpswitchboard/wiki/How-to-use-HTTP-Switchboard:-Two-opposing-views voor meer details over dit onderwerp.
* Bekijk ALLE externe verbindingen, mislukte of gepoogde, afhankelijk van of deze werden geblokkeerd of toegestaan (u beslist).
* Eén muisklik voor het whitelisten/blacklisten van een of meer aanvraagklassen volgens de bestemming en het type gegevens (een geblokkeerde aanvraag zal uw browser NOOIT verlaten).
* Efficiënt blacklisten: cookies verlaten uw browser niet, JavaScript wordt niet uitgevoerd, plug-ins worden niet afgespeeld, trackingpixels worden niet gedownload, etc.
* U hoeft niet slechts op één bepaalde beheerde blacklist (betwistbaar met veel ontbrekende vermeldingen) te vertrouwen waarbuiten niets anders kan worden geblokkeerd: u hebt de volledige controle.
* Gebruikersgemak: met uMatrix kunt u eenvoudig netwerkaanvragen die van een webpagina afkomstig zijn whitelisten/blacklisten, volgens een matrix via aanwijzen en klikken:
- domeinnamen (linkerkolom)
* van zeer specifieke
* tot zeer algemene
- type aanvragen (bovenste rij)
* cookies
* CSS-gerelateerde bronnen (stijlbladen en weblettertypen)
* afbeeldingen
* plug-ins
* scripts
* XHR (aanvragen door scripts)
* frames
* overig
Met slechts één klik kunt u een enkele cel, een hele rij, een groep rijen, een hele kolom, of de hele matrix blacklisten/whitelisten.
De filterengine van uMatrix gebruikt voorrangslogica voor het evalueren van wat er volgens de cellen die zijn geblacklist/gewhitelist is geblokkeerd/toegestaan. Hierdoor kunt u bijvoorbeeld met één klik een hele pagina whitelisten, zonder dat u dat herhaaldelijk moet doen bij nieuwe gegevens die op de pagina verschijnen.
Alle regels worden aan een bereik gerelateerd. U kunt bijvoorbeeld ‘facebook.com’ en ‘facebook.net’ overal blokkeren, behalve wanneer u een pagina op ‘www.facebook.com’ bezoekt. Op deze manier zal Facebook geen profiel van uw surfgedrag kunnen opbouwen.
Het doel van deze extensie is om het toestaan of blokkeren van websites, geheel of gedeeltelijk, zo overzichtelijk mogelijk te maken en daarmee gebruikers aan te moedigen om op hun privacy te letten.
Standaard bevat de extensie hosts-bestanden van derden met meer dan 62.000 afzonderlijke hostnamen (lijsten kunnen naar keuze selectief worden in- en uitgeschakeld).
Uiteindelijk kunt u kiezen hoe u op het internet wilt surfen:
* Alles standaard blacklisten, en whitelisten wanneer nodig (standaardmodus).
* Alles standaard whitelisten, en blacklisten wanneer nodig.
In beide gevallen heb u voordeel van de vooraf geleverde blacklists, zodat u op zijn minst basisbescherming krijgt tegen trackers, malwaresites, etc. U kunt al deze vooraf geleverde blacklists ook uitschakelen.
Uw keuze.

=====
Deze extensie is ook bruikbaar om te begrijpen wat de webpagina in uw browser doet, vaak zonder uw medeweten. U hebt de volledige mogelijkheid om te zien en te beslissen waarmee een webpagina communiceert, en deze communicatie tot bepaalde objectklassen binnen dezelfde pagina te beperken.
Het getal dat in het pictogram van de extensie verschijnt, komt overeen met het totale aantal afzonderlijke geprobeerde aanvragen (geslaagd of niet, afhankelijk van of deze werden toegestaan of geblokkeerd) door de webpagina.
Klik eenvoudig op de juiste vermelding in de matrix om een onderdeel te white-, black- of graylisten. Graylisten houdt in dat de status geblokkeerd of toegestaan van een andere cel met hogere voorrang in de matrix wordt overgenomen.
Rood vierkant = effectief geblacklist, m.a.w. aanvragen richting hun bedoelde eindbestemming worden voorkomen:
* Donkerrood vierkant: de domeinnaam en/of het type aanvraag is specifiek geblacklist.
* Vaalrood vierkant: de blacklist-status is overgenomen, omdat de vermelding is gegraylist.
Groen vierkant = effectief gewhitelist, m.a.w. aanvragen mogen hun bedoelde eindbestemming bereiken:
* Donkergroen vierkant: de domeinnaam en/of het type aanvraag is specifiek gewhitelist.
* Vaalgroen vierkant: de whitelist-status is overgenomen, omdat de vermelding is gegraylist.
De cel in de linkerbovenhoek van de matrix, de cel ‘alle’, vertegenwoordigt de algemene standaardinstelling waarmee u kunt kiezen of alles toestaan of blokkeren het standaardgedrag is. Sommige gebruikers geven de voorkeur aan alles toestaan en bij uitzondering blokkeren. Mijn persoonlijke voorkeur is natuurlijk het omgekeerde, alles blokkeren en bij uitzondering toestaan.
Deze extensie is ook nuttig als u het browsen wilt versnellen, bijvoorbeeld door alle aanvragen voor afbeeldingen overal te blokkeren.

Latest reviews
- (2025-07-11) Patrik Durdevic: BY FAR the best privacy extension. Just shows Google's true colours when it says it got remove because 'it doesn't follow best practices', when in reality it's because it gave users 'too much' control and was THE most effective at getting rid of ads.
- (2025-07-11) J Romero: best extension ever
- (2025-04-01) David S: Chromium is dead to me if they get rid of this.
- (2025-03-12) Rodney Hill: This is the best extension, hands down. Many thanks to all who have worked on it. I really wish it was still maintained....uMatrix has the perfect blend of a simple UI and powerful features to prevent tracking. It's something I'd be willing to pay for or donate to. It's that good.
- (2025-03-09) Nothingness: In anticipation of this change, I've switched to another browser. Not coming back to chrome.
- (2025-03-06) JW E: Chrome keeps trying to remove this from my browser, but doesn't understand how necessary it is to security. Chromium needs to add this as core functionality before ripping away extensions that improve security from browsers.
- (2025-03-03) Mario Leite: Writing this after Google just blocked this extension. So good it had to be blocked... shame on you Google.
- (2025-03-03) Antony Hutchison: Makes Chrome usable, both as a browser and as a development tool. I've switched to Firefox to keep this, and only keep Chrome around to access Google services (gmail etc) to try and keep Firefox clean of Google pollution.
- (2024-10-08) Alexy Rozman: We will miss this tool! Probably will migrate to another browser after MV3 will be enforced
- (2024-09-03) Mad Catter: Even though this addon is no longer actively developed, I still use & highly value it on all my browsers. It's a great shame that it will soon stop working. Alternative MV3 script blocker options are sadly lacking by comparison - spent hours looking yesterday & nothing comes close to the functionality of umatrix.
- (2024-08-22) Yotic C#: Best I've ever seen. Too bad it's hard to find on a search engine. Just a blazing fast for Selenium programming.
- (2024-06-28) Richie: Not user friendly, but powerful. You can direct very specifically what parts(javascript, xml, css, cookies, frames, media) of webpages are loaded and which aren't. It gives so much control in the hands of the user, whereas companies tend to stuff their pages chock full of stuff many people don't want. With umatrix YOU get to choose what they can load on your screen. Not actively developed for a long time now, but it's so basic that it will probably work without issues until chromium changes how webpages are loaded on a fundamental level.
- (2024-06-20) Kieron “KieSeyHow” Seymour-Howell: Quite simply the absolute best security addon for Chrome, or Edge. Nothing is better. A full in-browser firewall. I hope this addon is updated for the new v3 rulesets for Chromium browsers. This addon provides critical security enhancement for Chromium browsers.
- (2024-06-09) AK xyz: Good for monitoring, good for blocking especially when you may be looking at banking, etc. Thank you.
- (2024-05-20) Cuvtixo D (cuvtixo): It's great for advanced users, for the time being. The project is no longer being developed (since 2021) and the Github repository has been archived. It will probably, mostly, continue to work for years. Probably. Apparently you can get some support from uBlock github site, I have no knowledge on the details of this.
- (2023-12-17) L8 Very: Perfect
- (2023-08-28) J J: It's very good but it also creates web problems that block pages. It's not user friendly.

- (2023-08-08) Вадим Головко: Прекрасное расширение. Огромная благодарность создателям! Пойдет опытным пользователям. Работает лучше всех адблоков, юблоков и так далее. Поражает функциональность расширения и возможности гибкой настройки под каждый отдельный домен.
- (2023-07-31) Pro tric: Works fine. I use it most for stopping any malicious script. Har använt umatrix länge nu. Främst för att stoppa ev elaka script från 3-parts-siter som kan vara infekterade. Sen går det mindre processorkraft om webläsaren inte måste köra en massa script hela tiden.
- (2023-07-10) タメル: Twitchから配信者をクリックしても画面がぐるぐるとローディング状態で開かない
- (2023-03-11) Kurt Amesbury: WOW! For years I've had to tolerate all the GARBAGE Fox News loads on its web pages. With this extension, I was able to eliminate all the parts I DON'T want to see. So no more ads. A lot less images. Just the story and the comments. That's it! The extension is a little complex at first, but once you get the hang of it, it's VERY cool. (And like most people, I didn't read the documentation - so if it was "complex", it could be mostly my own fault!) One thing I'd recommend is a "quick start" example. Put up a sample web page and walk users through how to filter out different parts. But bottom line - this does EXACTLY what I was hoping it would do. +++++

- (2023-01-14) Tony Kujawski: Humbly stating I provide super geek services, I red/blue team, audit and certify HIPAA/HITECH, PCI-DSS 3.2, and SOC II type2. I use three tracker/adblockers. Ublock origin, NoScript, and uMatrix. Ublock doesn't provide a clear interface for exactly what blocking is occurring in the background, while it does provide an interface to show you what sites were pinged, I frequently find I am required to disable it, before the functionality of a website works correctly. No Script is much more simple and fluid, I would recommend for the intermediate tech savvy, you can quickly trust a single tab, or you can "temp trust, always trust, or never trust" each website that the current one connects to such as ad servers and content delivery networks. If set the always temp trust the site you go to, and are willing to toggle a few permissions, you can lock in your choices and export/import/sync with browsers. Import and exports are not cross browser compatible, but are if using same framework (Chrome to MSEdge / EpicPrivacy / Adblock / (Opera / OperaGX are CHINESE OWNED) and Firefox to Firefox_Focus / Brave / TOR_Preconfigured / Waterfox). uMatrix has similar export features and is more fine grained and configurable per-site and domain. Offers ability to use the highest rate block list should you choose to, this is for the more technically savvy who seek fine grain control, all things considered, if you are only going to use one, this is the one I take the time to configure the way I like and it always puts the "ad site / bad sites blocked at the bottom. It also has a greater visibility into what is happening and a much greater fine grained control.

- (2022-12-19) Inner Universe: Тупо не грузит полстраницы любого нужного сайта. потоковое видео вообще невозможно смотреть - на месте окна с видео пустой прямоугольник. Бесполезная хня.
- (2022-11-04) COW KING (THE COW KING): 概念很棒，但是内置拦截规则不行。开了之后包括Youtube，gmail，哔哩哔哩，pornhub等绝大多数常用网站都无法正常使用。也没有黑名单模式，所以就只能关了吧
- (2022-10-26) Oscar Cerino: Excelente extensión para bloqueos de noscript, funciona muy bien para lo que requiero. GRACIAS!!!
- (2022-10-21) Сергій Макаренко: Дуже якісний антибаннер
- (2022-07-28) Roman Petrov: Великолепная реализация отличной идеи.
- (2022-06-29) Peter Williamson: A great security app, but a real pain at times. Every time I go a site for the first time I have to make sure I turn off either specific elements or uMatrix as a whole if I trust it, then save it. I also find it's a little too "trigger happy" when I click on a link from an email or site I trust. Case in point, if I have a link to a tracking site regarding an order, if I click the link uMatrix will block it. I have to go into my settings, turn off uMatrix, click the link to track my order then turn uMatrix back on again. Perhaps there's something I've missed in the settings, and I understand why it exists in the first place, but it can be frustrating when I know a link/site is safe.

- (2021-10-26) Cristobal Rodriguez: Error para Desarrolladores, las webs en otro idioma uMatrix bloquea poder traducir las webs del ingles al español, por ejemplo esta web https://www.macrumors.com/, es una lastima la voy a desinstalar y ademas la publicidad de todas las webs las bloquea bien pero deja el espacio de la publicidad en blanco. uBlock Origin y otros bloqueadores no dejan el espacio de la publicidad en blanco y eso esta mal para leer la webs
- (2021-10-19) Béla Tóth: Rendkívül hasznos segédlet. Nemcsak azért, mert kizárja a harmadik felek közbeékelődését, hanem részletesen szemlélteti, hogy az aktuális weboldal milyen scripteket, kívülre mutató linkeket, adatbekéréseket stb verszélyforrásokat tartalmaz. És ezek működését akár részleteiben ki lehet iktatni.

- (2021-01-21) Clemens Ratte-Polle: Very complicatedt, but seems to sum up all AdBlockers, Anti-Trackers and much more :) What it needs? Not only yes or no, red or green. Additionally options: Temporarily for the session in orange and Blue for permanent but globally allowance over all URLs. This would be finde :) Could you please make the Klick-Board scrollable, i cant see the bottom options - my screen resolution is not so great.^^
