@PotentialUser uBO is able to do this because Firefox has API which supports CNAME uncloaking technique. It was being done mainly to combat 1st party tracking. Unfortunately, Chrome and other Chromium based browsers don't seem to support this. So that's why it behaves differently on Chromium. Check out the links below for further reference.
uBO version 1.25.0 changelogs
Address 1st-party tracker blocking #780
Precisely.
The FF API is unique to it, neither Chrome/Chormium have similar support.
Thank you both for replying. And I appreciate the links
@redsworn! I took a look at the GitHub pages redsworn linked and did some of my own research on the topic as well and have a question for both of you (feel free to both reply if you can
).
I found this article (among many others) detailing this recently-released feature. It states the resources are highlighted in
blue with the uncloaked sites displayed in a smaller font size under the canonical names. I've included the article's example image in this post. As you can see in the image below, a
cloudfront.net domain was attempting to mask a
mailmunch.co domain (which the Firefox version of uBO noticed and highlighted in
blue).
However, when you take a look at the two images I supplied in my earlier post in this thread, in uBO Firefox,
neither the
jagex.com, nor the
runescape.com domains, were
blue or had uncloaked sites listed in a smaller font underneath. Forgive me if this is a misunderstanding but doesn't this mean
jagex.com is
not loading up as hidden first-party tracker? It is simply loading up like any other domain would and Microsoft Edge just didn't pick it up for some odd reason but Mozilla Firefox did?
Which means in this case (only), this doesn't have anything to do with Chromium-based browsers lacking the ability to uncloak CNAMES. Because if this was a CNAME issue, then in Firefox, the
jagex.com domain would be listed under the
runescape.com domain in smaller font and both would be highlighted in
blue to show that it was attempting to sneakily load up -- similar to how the
mailmunch.co domain was listed under the
cloudfront.net domain with both highlighted in
blue in the image above.
Again, my apologies if this is completely off the mark. I am a new user to uBO (my second day messing with it) but I thought I'd ask this question anyway since it was something I noticed.
Thanks once again for your replies you two!

Also, off-topic but do you still use Brave on a regular basis
@oldschool? I ask because I read the recent "scandal" regarding some affiliate links or something and it didn't seem like such a big deal to a layman like me. But I've seen others say you use(d?) around here so I'm interested to hear your opinion.
