Be aware that especially on Firefox even the Arkenfox project mixes up
- removing "everything mozilla" including update infos and useful telemitry
- disabling annoyances
- reducing sent data and fingerprintability (privacy)
- disabling or limiting components that increase attack surface (security)
I think NoScript is a great example of Security and Privacy in one tool. For sure you can run all that tracking Javascript in a container, but it is more risk and at the same time a data kraken.
Vanadium sends nearly no data, it is also degoogled, which works well also on Desktop Chromium, even using your Distribution package.
But simply "not sending data" doesnt mean that it allows
- persistent site data containers
- fingerprinting resistance
- i.e. less identifiable data about device sent
- & more general fingerprint
- & randomized values
Vanadium does nothing of that afaik, probably reduces data collection but nothing fancy like RFP on Firefox. Also its UI for site-based settings sucks and is very limited. Things for containers and cookie allowlisting (the rest gets always cleared) are missing a lot.
Even MS Edge has more QOL settings, Brave is poorly very bloated, not sure about Vivaldi. Chrome & Chromium have nearly no settings, I have no idea why people use that Browser.
Using hardened_malloc on Secureblue Linux, I am trying to use Chromium and it is totally okay, just the sync is really missing. And needing an extension to get a blank new tab page. And more. But it is okay!
