Image from store uMatrix
Description from store uMatrix: A point-and-click matrix-based firewall, with many privacy-enhancing tools. *For advanced users.* CHANGE LOG: https://github.com/gorhill/uMatrix/releases uMatrix put you in full control of where your browser is allowed to connect, what type of data it is allowed to download, and what it is allowed to execute. Nobody else decides for you: You choose. You are in full control of your privacy. Out of the box, uMatrix works in relax block-all/allow-exceptionally mode, meaning web sites which require 3rd-party scripts are likely to be "broken". With two clicks, uMatrix can be set to work in allow-all/block-exceptionally mode, which generally will not break web sites. See https://github.com/gorhill/httpswitchboard/wiki/How-to-use-HTTP-Switchboard:-Two-opposing-views for more details on this topic. * See ALL the remote connections, failed or attempted, depending on whether they were blocked or allowed (you decide). * A single-click to whitelist/blacklist one or multiple classes of requests according to the destination and type of data (a blocked request will NEVER leave your browser). * Efficient blacklisting: cookies won't leave your browser, JavaScript won't execute, plugins won't play, tracking pixels won't download, etc. * You do not have to solely rely on just one particular curated blacklist (arguably with many missing entries) outside which nothing else can be blocked: You are in full control. * Ease of use: uMatrix lets you easily whitelist/blacklist net requests which originate from within a web page according to a point-and-click matrix: - domain names (left column) * from very specific * to very generic - type of requests (top row) * cookies * CSS-related resources (stylesheets and web fonts) * images * plugins * scripts * XHR (requests made by scripts) * frames * others You can blacklist/whitelist a single cell, an entire row, a group of rows, an entire column, or the whole matrix with just one click. uMatrix's filtering engine uses precedence logic to evaluate what is blocked/allowed according to which cells are blacklisted/whitelisted. For example, this allows you to whitelist a whole page with one click, without having to repeatedly whitelist whatever new data appear on the page. All rules are scoped. For example, you can block `facebook.com` and `facebook.net` everywhere except when visiting a page on `www.facebook.com`. This way Facebook won't be able to build a profile of your browsing habits. The goal of this extension is to make the allowing or blocking of web sites, wholly or partly, as straightforward as possible, so as to encourage users to care about their privacy. The extension comes with 3rd-party hosts files totaling over 62,000 distinct hostnames (lists can be selectively disabled/enabled according to your choice). Ultimately, you can choose however you browse the net: * Blacklist all by default, and whitelist as needed (default mode). * Whitelist all by default, and blacklist as needed. Either way, you still benefit from the preset blacklists so that at least you get basic protection from trackers, malware sites, etc. Or you can disable all of these preset blacklists. Your choice. Randomly assembled documentation: https://github.com/gorhill/uMatrix/wiki ===== This extension is also useful to understand what the web page in your browser is doing, often without your knowledge. You have full ability to see and decide with whom a web page communicates, and to restrict these communications to specific classes of objects within the web page. The number which appear in the extension icon correspond to the total number of distinct requests attempted (successfully or not depending on whether these were allowed or blocked) by the web page. Simply click on the appropriate entry in the matrix in order to white-, black- or graylist a component. Graylisting means the blocked or allowed status will be inherited from another cell with higher precedence in the matrix. Red square = effectively blacklisted, i.e. requests are prevented from reaching their intended destination: * Dark red square: the domain name and/or type of request is specifically blacklisted. * Faded red square: the blacklist status is inherited because the entry is graylisted. Green square = effectively whitelisted, i.e. requests are allowed to reach their intended destination: * Dark green square: the domain name and/or type of request is specifically whitelisted. * Faded green square: the whitelist status is inherited because the entry is graylisted. The top-left cell in the matrix, the "all" cell, represents the default global setting, which allows you to choose whether allowing or blocking everything is the default behavior. Some prefer to allow everything while blocking exceptionally. My personal preference is of course the reverse, blocking everything and allowing exceptionally. This extension is also useful if you wish to speed up your browsing, by globally blocking all requests for images as an example. ===== BUGS, ISSUES: https://github.com/gorhill/uMatrix/issues SOURCE CODE: https://github.com/gorhill/uMatrix (GPLv3)

  • (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.
  • (2021-11-25) Roy Williamson: It just worked! Wow. Seriously impressed. These days extensions overpromise and under deliver. this is the opposite.
  • (2021-11-13) Nurak Ibinski: Wichtigste Erweiterung überhaupt.
  • (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.
  • (2021-10-14) Paul Mullane: If you need help.. great little tutorial here https://proprivacy.com/privacy-service/guides/lifehacks-setup-umatrix-beginners
  • (2021-09-30) Fauzi Bin Ridho (FONZ): the best security extension just got a few updates. i do hope it can make a permanent comeback though. thankfully it did get a few maintenance patches. lets hope umatrix can see a reason to keep being alive and well...

  • (2021-06-22) Martin Liebetruth: Standard-Entwicklertools des Browsers sind wesentlich ausführlicher

  • (2021-04-14) Ramón Telleria: Lo empecé a usar en el 2017 y me funcionaba bien con facebook; pero ahora que lo he vuelto a usar después de estar sin computadora por 3 años, no me deja cargar facebook.
  • (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.^^
  • (2020-12-17) Sébastien Marchandeau: Très bonne extension. Malheureusement la synchronisation ne fonctionne plus depuis quelques jours...
  • (2020-12-11) Ken Heisenberg: Top privacy/productivity addon. This one + uBlock Origin are a must extensions.
  • (2020-11-29) Vanish Pro: Лучшее что я когда-либо ставил
  • (2020-11-24) Yasemin Elmalı: Harika bir site istediğiniz zaman ücretsiz video indirip izleyebilirsiniz ben cok beğendim
  • (2020-10-08) Noel D. Smith (nds80): If you want pretty, it will cost you. Professionals don't care about looks, we want power and versatility. This thing replaces every other script blocker with less resource consumption than any given one. Feedback: I recommend the developer create some reminder that you're spoofing by default, that seems to be a common sticking point. (Color the button blue/yellow?) You will also eliminate 90% or more of all dissatisfaction with a 5 second graphic showing people how clicking "all" from red to blank to green works. Most of the complaints don't even know why they're using this, let alone how.
  • (2020-09-08) Francis: 不明白为什么默认要把Google translate加入拦截名单,搞得chrome自带的翻译每次都不能用,还要单独设置
  • (2020-08-31) Kris Karlov: Its good, but extremely annoying. I have to disable it a bit on every website I use regularly. Still nice.
  • (2020-08-27) JESUS NAVARRETE: buenisima
  • (2020-08-22) Joe G: The best way to see what a page is doing or hanging on. All browsers should have this by default.
  • (2020-08-21) KirKirMUrGames: Дуже гарна аплікація.
  • (2020-08-20) halo kick: Simple and beautiful. Learn it Google.
  • (2020-08-16) RoseNo4X: I can't believe this is made by someone from Quebec ! Used it for years with uBlock Origin.
  • (2020-08-14) elektro inside: Brilliant!! And extremely useful!
  • (2020-08-13) Подберёзкин Владислав: Спасибо создателю сего чуда. Рекламы как не бывало.
  • (2020-08-12) Bobby Ankony: uMatrix is awesome. I have used uBlock for a long time, and it feels like it's functionality has slowly eroded as websites get more advanced at detecting adblockers. uMatrix really brings control back. I'll echo what others say that there is a bit of a learning curve, but after about a day I mostly got it. Basic website functionality usually works right out of the box, with many more advanced / interactive features requiring some permission adjustments. I've grown to really like this though - it really strips out the fluff from most websites.
  • (2020-07-29) dj osearth: I love that this extension is available if I ever need it but for now I'll stick to *uBlock Origin* with it's default block lists that auto update from the publishers for those block lists. This is an extremely powerful extension & I always appreciate the ability to install this if I had the need in the future but for now I'm going to remove it & stick with the more basic *uBlock Origin* (but also a rabbit hole in it's own right:) ..
  • (2020-07-20) Mikey Teen: Literally upon adding this extension and testing it on youtube it prevents the videos from loading properly. Removed.
  • (2020-07-05) Mark Ridgway: Fully granular information and control. Perfect.

  • (2020-03-13) Tony Zhu: This is a great extension. One thing hope to improve in the future version, add a color theme to support dark mode, currently with dark mode, some text and icon not able to see. thx!
  • (2020-02-27) Johan Rylander: Väldigt enkelt att använda. Tack! (thanks!)
  • (2020-02-17) Artem Usov: Прекрасно и быстро выполняет свою функцию. Спасибо большое!
  • (2020-02-10) Andrey Fedorov: There's a really minor learning curve (much less than it looks like at the outset), but on the other side is a great sense of empowerment over a faster, safer web, with so much of what the browser does "out of sight" now controlled by you, the user, not the sites you're visiting (or the iframes & tag managers they've included!).
  • (2020-02-06) Jerry Diamond: This is the best, most ingenious extension ever! Finally you can control your browser instead of the browser controlling you! Choose what data you allow and block what you don't want. No more pages killing your PC, eating up your CPU, memory, hard drive, endangering your security! uMatrix lets you block or allow every element of the page with fine precision! Raymond Hill, you should get the Medal of Freedom for writing this gem!!!
  • (2020-01-17) Cobin Bluth: amazing features, allow or block anything in your browser, its like having full control of something you operate
  • (2020-01-15) DKone: How does this not have more reviews. This is a game changing extension. YOU now have complete control (and can see) everything that is trying to come through when you go to a site. Don't forget to ad Ublock by the same developer.
  • (2019-12-11) Piotr G: Genialne narzędzie!
  • (2019-12-06) Demet Yilmaz: Amazing extension. I feel like I am in control again.
  • (2019-11-11) Markus Varis: If it could just sync. I'm using it on Chrome and uni desktops that reset the settings every time. It's unusable for this purpose, MS Office web portal needs so much whitelisting every time that it's just unpractical. I have to remove it.
  • (2019-10-21) Reid Rivenburgh: Excellent, fine-grained way to control what your browser does.
  • (2019-10-05) connardman: Easy to use and works perfectly. Thanks :D
  • (2019-09-30) JON Cunningham: Its working great! I use NoScript as well for extra options.
  • (2019-09-18) Marcello Triulzio: top

  • (2020-04-01, v:1.4.0) Wes M: Control panel popdown has sizing issues in Vivaldi
    uMatrix's dynamic control panel sizing is not picking up the actual size of the entries in the grid... it seems to be picking up the sizing of the previously touched extension, such as ublock origin, or other (also Shortcuts for Google Products). So the display of the uMatrix panel is truncated and will not scroll... Unable to reach grid entries after the first couple entries Steps: - Install uMatrix and uBlock Origin - Pull down uBlock Origin control panel popup - Pull down uMatrix control panel popup Results: - Other Chrome extensions control panels are their normal sizes - uMatrix panel is set the the size of the panel from the previous extension used Note: This doesn't seem to occur right away... Occurs after some use, so there may be an additional factor here I yet to determine. uMatrix is the only panel that has the issue, though. The other panels continue to display normally.
  • (2020-01-30, v:1.4.0) Weird umatrix field
    I got in the field of umatrix in Chrome. This field with the submask shows in every site/domain I am on. I asked you the same question a couple of months ago but i never got any answer from you back then. This problem is not present in Firefox with umatrix only in Chrome. Thanks!
  • (2020-01-11, v:1.4.0) n ascentt: Stopped working for me a month ago
    umatrix stopped working for me in chrome a month ago, i'm not sure how to best describe it, but it doesnt detect anything in the ui ( there's no numbers in the grid of umatrix) so it's as it it's claiming to not block anything, and yet everything on websites is being blocked including payment processor frames, so websites cant be used at all, and theres no way to whitelist, and i'm fairly sure it's blocking things i previously whitelisted globally i would've uninstalled and reinstalled umatrix but cannot find a way to export/import whitelists

  • (2019-01-22, v:1.3.16) John S Wolter: About about for websites listed by uMatrix
    The short explanation is that I want more background information about uMatrix listed sites. It would be a good start to understand the business of a website service. Sites could be simple advertising, trackers, data scrapers, and a whole long list. Second would try to indicate what that company or Non-Government Organization, NGO, is doing. Results of using anti-virus' sites' lookup features usually results in terse site statements like "No malware distribution yet". I looking to better understanding These don't have to be detailed. A statement as simple as "Selling gathered data to its customers" or "Delivered Ads platform". Add some anti-malware warnings. Cheers
  • (2018-10-17, v:1.3.14) Page doesn't load properly even though all scripts are enabled
    In this case I'm looking at the americastestkitchen.com website. If I turn off Umatrix via the "power button" the site loads fine. If I turn Umatrix on, go through the list of scripts and enable every single one (even the blacklisted domains) the top of the page is completely messed up with huge black images and some text. I'm not understanding how "off" and "all enabled" aren't the same thing. So, in this case, I can't use UMatrix on this site because the pages won't load properly. It's almost like there is blocking going on in the background that I can't see or manage. Love to hear any solutions for the issue. Thank you!
