uMatrix

We will miss this tool! Probably will migrate to another browser after MV3 will be enforced

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.

Best I've ever seen. Too bad it's hard to find on a search engine. Just a blazing fast for Selenium programming.

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.

Good for monitoring, good for blocking especially when you may be looking at banking, etc. Thank you.

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 The project is no longer being developed (since 2021) and the Github repository has been archived.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.

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.

Perfect

It's very good but it also creates web problems that block pages. It's not user friendly.

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. +++++

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.

Learning curve is a bit steep, but it seems like amazing tool so far.

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.

It just worked! Wow. Seriously impressed. These days extensions overpromise and under deliver. this is the opposite.

If you need help.. great little tutorial here https://proprivacy.com/privacy-service/guides/lifehacks-setup-umatrix-beginners

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...
