From the linked GitHub webpage:
All builds are experimental, so unexpected issues may occur. Helium Browser for Android only attempts to improve security and privacy where possible. For better protection on Android, you should instead use GrapheneOS with Vanadium, which additionally integrates patches into Android System WebView and provides significant kernel and memory management hardening on the OS level.
I wouldn’t recommend browsers developed by a single person and in an experimental state-part of the reason why I don’t recommend Cromite.
The original Vanadium is great, but the lack of proper content-blocker integration is a big privacy trade-off, in my opinion. Vanadium only provides a per-domain blocker solution, which is based on the very small set of EasyList.
A good Chromium-based alternative would be Brave, as it has a good content blocker that attempts to recreate the full feature set of uBlock Origin.

Would be nice if you could correct it in your original post too.
