I found it funny that people use Chromium-based browsers and pretend they're unique.
If you want freedom, features and manifest v2 then just use and support Firefox.
Why is a different browser with completely different UX that is using Chromium not unique?
They are unique. The UX of Arc was (and still is) MUCH, MUCH better than Chrome's. Or Firefox's. Or Helium's. Or Edge's.
