Would have added this to an older post, but it had been closed.
Only discovered this browser by chance. Go Gnome!
Learned so far:
Built on WebKit (Safari’s engine) shares the same rendering engine and tracker-blocking as Safari.
No extensions like Firefox or Chrome, but can add custom user scripts.
Installed web apps launch in standalone browser windows.
Flatpak runs the latest version.
Gnome is pretty good. Got some good stuff.
Well, I don't like flatpak, period. Looking forward to Ladybird browser due out next year and not based on any existing engine, being built from the ground up.
Yeah, had a look at it after you mentioned it. Linux gets it first, not Windows! 
I like Gnome web because you can see which trackers each site is using.
I've used Epiphany for a while and was quite satisfied with it. But in the end there were a little too many nuances and limitations for my taste, perhaps most notably the lack of extensions. That, and the fact that going forward only the Flatpak option is available.
In fact, it looks like it's gotten even worse over time. Fewer options available, fewer controls, lack of customization options... I just don't see how it can compete with any of the many alternatives that are much better in just about every way 
Yes, well, it's not a serious contender - but it's got a home here. Found a few uses for it. YouTube without ads and no extensions, for one.
A Gnome browser is tempting for many reasons. But no way I'm getting online without an ad blocker at a minimum.
I am surprised that Gnome named it Epiphany rather than Etch-A-Sketch.
the difficulty the gnome browser has with utilising extensions is like chalk and cheese because webkit (apple) is almost incompatible with manifest 2 or 3 (mozilla), whereas before, when it used gecko, they were able to...
think they dropped mozilla because they weren't happy with the direction
yeah, had to look it up how to pronounce it 
like gnome web better
To Epiphany and beyond 
Note: Etch-a-sketch is a Registered Trade Mark.
Interesting.

Observations on Browser Privacy
You noticed some interesting differences when visiting the same website with different browsers and their blockers. Here's a summary of what you found:
Brave's Shields blocked 2 trackers.
uBlock Origin blocked only 1 tracker.
GNOME Web blocked the most, with 4.
This was surprising because the blockers are all supposed to do a similar job. The key takeaway here is that they each use a different set of rules and methods to find and block trackers.
What's Up With Google Tag Manager?
You pointed out that Google Tag Manager (GTM) was a frequent culprit. This is spot-on. GTM isn't a tracker itself; it's a tag management system that lets websites easily add various scripts—including lots of trackers from places like Google Analytics or Google Ads.
It's a persistent problem because so many websites use GTM.
How the Blockers Differ
The reason for the different numbers and how they handle GTM comes down to their core philosophies:
Brave and uBlock Origin are great, but they primarily use filter lists. Think of these as a massive "do not call" list for tracking scripts. They block the trackers that GTM loads, but they don't necessarily block GTM itself.
GNOME Web is different. Because it's built on WebKit (like Safari), it uses a clever system called Intelligent Tracking Prevention (ITP). Instead of a simple list, ITP is a behavioral system. It doesn't just look for specific tracker URLs; it observes how a domain like GTM acts. If it sees GTM trying to do things that trackers do, it steps in and blocks or neuters those actions.
This is why GNOME Web blocks more and seems to handle GTM without a problem—it's more aggressive and intelligent in how it identifies and stops tracking attempts.
