rabblevox: Brave is based on the open source Chromium, not Chrome. I know it sounds like a "distinction without a difference", but it's actually quite significant. According to the best brains I know, Google has exactly zero hooks into, or control over, any Chromium based browser.
I've actually recently started moving back to Firefox from Chrome (Windows) and Chromium (Linux).
Reason being that in one of my old low-power laptops (some old dual-core laptop with 3GB RAM, running Linux Mint 20.3 64bit) I started noticing that Chromium seems like a real hog. I am not sure why but if I go to Youtube or gog.com or various other heavier sites with it, for some reason it makes the whole system very unresponsive, long pauses where the machine does nothing, constant CPU usage spikes to 100% etc.
Also, on my more powerful work laptop, Chrome nowadays has an odd habit to make the whole screen white if I hover over any of the videos in Youtube (I think that starts playing the video in a smaller screen automatically).
At the same time, on Firefox, those same sites work fine and the system is very responsive even on that old low-power laptop. And on my more powerful work laptop, Firefox doesn't have that same problem in e.g. Youtube.
Based on that, it just appears Chrome and Chromium is a real hog without any good reason, so I rather use Firefox for now. At least I don't see any benefit to using Chrome/Chromium, only downsides like that extra resource usage.
I don't use any extra plugins or add-ons in Firefox, other than those that come with it by default. So I have no idea if some AddBlocker Super Plus thingamalingies affect sites.
Edge is in a category of its own... currently I am using it only on my Windows 11 laptop as it is still the only browser I've installed there (I should really install Firefox there too)... Usually it works fine, but from time to time it just fails... even with Microsoft's own services!
For instance, a week ago I helped a relative of mine (a kid) to migrate his Minecraft account from Mojang to Microsoft, as Microsoft owns Minecraft nowadays and they are going to shut down the Mojang accounts.
I performed the migration according to the instructions, but where it should launch a web browser to the migration site, it failed. It wouldn't launch that site, but just show some kind of "sad face" icon on the browser. (That browser was Edge, which is the default browser on that Windows 10 PC where I performed the migration.)
Then it occurred to me to copy&paste that URL from Edge to Firefox... and it worked! Then I could finally perform and finish the migration.
So ironic that Microsoft's own browser would just fail with their own game (Minecraft)... I had some similar issue before where I could not use some online service and then their online help told me they haven't tested it with Edge, and sure enough it worked fine with Firefox instead.
