What's wrong with using TOR ?

As long as it is not based on the ubiquitous Chromium engine (or whatever its name is) a secure european browser would be much needed. I don't know if a revival of the former Presto engine from Opera is technically or financially feasible but it would be great. Another option is to use the Firefox engine, because I guess that to develop an independen engine would be a too daunting task.

I agree this would be a great idea. I use Firefox but I am not sure its promises of privacy can hold up when it is a free service.

That's quite an accusation ("Chrome is snap shoting [sic] and keylogging..."). Can you substantiate it?

Try Pale Moon. I doubt you'll be disappointed.

Yes, a browser MacAphee would use.

Should partner with Brave on this if you choose to do it vs reinventing the wheel.

Firefox is doing a Privacy based browser.

"With companys like google buying up all the alternative browsers I think this a needed program/app. What good is the secure email when Chrome is snap shoting and keylogging your protonmail logins."

Google isn't the one doing this. Some third party analytic software does keylog user interactions with the website. I can assure you those third party analytic tools are not present on protonmail.com.

Also since a browser is client software, and most internet tracking is not from the browser but from third parties, a Proton Browser wouldn't have any impact on tracking. The extensions mentioned below will.

If you're looking to conceal your physical location, consider ProtonVPN.

As other have said, try existing browsers that do this.

Some good extensions are:
- uBlock Origin
- HTTPS Everywhere
- Privacy Badger
- uMatrix (advanced)

A browser is out of the scope of this project, and is very complicated.

You can try Waterfox, it's Firefox with telemetry and startup profiling striped out.

Try using Firefox with extensions like Privacy Badger (https://is.gd/u9fdEU ). Or, if you really want privacy, use Tor (https://www.torproject.org/ ), although it is pretty slow. Also, ProtonMail offers a VPN too (https://protonvpn.com/ ).
