A Review of ungoogled-chromium Patches: https://qua3k.github.io/ungoogled-chromium
It pains me to say this, but don't use Ungoogled Chromium. I've said for a while that it was dangerous to rely on them to provide updates, exposing you to n-days. But I didn't know they also disabled CFI.
I suggest you use Chromium or any Chromium-based browser instead and opt-out as many things as you can.
Just a single-user instance, nothing fancy here. I won't bite, I promise.
