AmIUnique VS ungoogled-chromium-archlinux

I go the opposite way. I trust a company that takes my money to pay its costs to keep my privacy. As opposed to a company who "doesn't know who I am". (Apart from unique fingerprint https://amiunique.org/ over many queries over many months)

You're not completely wrong, but that ship has sailed a long time ago: https://amiunique.org

Until browser fingerprinting is addressed, there will be no real privacy.

You are. Compare the fingerprints of your two browsers: https://amiunique.org, https://coveryourtracks.eff.org. Very likely, the fingerprints are very similar. For anonymity, use Tor.

It’s mostly client-side stuff, you can access browser’s properties like canvas size, plugins, hardware, sensors. Try visiting https://amiunique.org/ You’ll get the idea.

There is a working patch for 103 now.

You can build Ungoogled Chromium from the AUR or get a binary through the OBS repository by following the steps here

I've never run into any codec issue using either the AUR version or the one compiled by GitHub Actions or OBS which are all linked here. If you have a problem with those please open an issue and I'll look into it

In this case, there are repos with precompiled binaries for Ungoogled Chromium, like the Chaotic AUR and OBS: https://github.com/ungoogled-software/ungoogled-chromium-archlinux/releases

I assume you're using Manjaro, so it should be in the AUR, or you can get a custom repo with prebuilt binaries here.

There was a recent update to the flags in makepkg.conf that cause build failures: https://github.com/ungoogled-software/ungoogled-chromium-archlinux/issues/123

Prebuilt Arch binaries exist here: https://github.com/ungoogled-software/ungoogled-chromium-archlinux#ungoogled-chromium-archlinux

Or, just download binaries that are approved by the source
