Yes, I suggested Vivaldi in the article.

Chromium on Linux - but it still has the google blobs.

There's Ungoogled Chromium if you're interested.

brave is still the best in terms of compatibility, features and efficiency which is why popular linux distros Nobara and Zorin use it as the default

Not a great example, but the ERP I use for work doesn't support Firefox and has some minor issues due to how Firefox handles frames differently from chromium based browsers.

If you use a browser back, the site goes all the way back to the home page instead of the previous menu you were using, because they put a whole extra layer over the entire site to handle navigation.

I haven't noticed a website outright blocking Firefox in a while, in part because Firefox devs are staying on top of it with overriding a lot of site blocks. The issue I run into the most is reduced video quality in Google Meet in Firefox, so I switch to Safari or Chromium when I need to do calls there.
