No need for this. Users can use Tor and go to the Proton Onion site instead.

Firefox is open source and overall a great browser. If Proton DID develop a relatively simliar browser, however, I would use it and even buy it if it was charged. Still, Firefox is hardly equivalent to Chrome.

-1 vote. Firefox, Brave, Tor work great.
To detected and block trackers use Privacy Badger by EFF.

I also use the free Epic privacy browser. I would prefer that ProtonMail add other features like a calendar instead of creating a browser that already exists. Maybe they could partner up together, though?

I agree. I use Epic browser for Mac with built-in VPN and proxy. It never keeps a history so it's invisible inside and out. I use Opera for normal business matters because Epic is too invisible it doesn't quite work with everything.
I agree with some of the comments, that another well-built, trustworthy browser in the mix would be good.
I agree with others who worry that the Proton engineers might be overtaxed.

Yes,I am totally agree with the idea of a strong " Proton Browser" . Please,more encryption, more security features and more servers of Protonvpn.

Independent and new web browsers are a good idea. Not even to do with tracking but to do with where you are directed too. Google, Firefox etc. determine what pages you get to see, what's at the top of the list, or if they feel a source is untrustworthy they have stated they will not publish it. Who gets determine such things they do. The reason why I use proton mail is because I don't trust big brother, and I don't trust the big search engines. An alternative non-tracking search engine is a goo idea.

I use firefox with Duck Duck Go for searching because of the less tracking. something like that or better would be great.

This is a bad idea, browsers have to be maintained the team would have no time to work on email features if they have to maintain a browser. There are already a ton of alternatives.

I'm with the last guy but I think a free secure European vpn service is also needed.

Using combinations like duckduckgo combined with firefox along with the free ghost vpn service is a little bit annoying to try to get what you want from one.

If protonamail could combine these services so everything was under one roof that would be great.

Thanks to protonmail in any case for the services they already provide.

I second FF and https://www.privacytools.io

Honestly don't waste time on this, for me it's all about allowing users to re-key and add exporting to their existing private keys moving them from 2048 to 4096. With that change and PM Bridge continuing to keep up with their Unix integration it will be a good 2018.

I don't get this one. We already have brave which is the no-tracking browser, why duplicate the efforts?

Duck Duck Go doesn't track.

Yes, it would be nice to browse with Proton... and a free VPN is a must. Non-proprietary operating systems are also important, in my opinion. I'm sure all these are welcome technical challenges / pastimes for the guys at CERN and MIT : am I wrong? Also, Proton is already charging for some services, right?

No need. There is Iridium Browser already.

there are already open source and relatively secure browsers. that would be a huge effort and it would divert time and money from other more relevant tasks. what is next - a new OS?

One more suggestion would be to allow to connect to open VPN or TOR through that browser easily.

You should just go with Brave, honestly.

I don't think they'll ever challenge themselves with that daunting task.

Regarding the sentiments and upvotes for this you guys should try out https://www.brave.com/ it seems everything everyone is wanting and more.

In 2018 its necessary fixes and issues without a doubt will be fixed and are still to implement a number of suggestion by its users but I think this will be met within this year. It's amazing to see how far they've come.

Honestly try out Brave and you won't bother upvoting this topic any more.

One other thing they're in the process of implementing TOR on a per-tab-basis (TPB) Tor Private Browsing

Firefox in private mode, Tor web browser, Brave. These browsers should do the job.
