Bad idea, Firefox and Tor Browser are already excellent.

no support. there are plenty of firefox derivatives that focus on privacy and security, also a few chromium and safari derivatives. we do not need another.

try k-meleon or pale moon or midori or one of many others.

Firefox team is working different ways to improve privacy and security. They are steady and active. On the other hand, we also have Tor browser. So, I think it's better for ProtonMail to focus on E-Mail, Contacts, Calendar, Chat and mainly Cloud Drive.

Amen! their is many browswers out their and I have not been impress, I wished they would build one, if they do I have many ideas to imput things to make it safe and secure and clean of crap.

Didn't see it mentioned, but what about a stand-alone email app, like in the old days? Even build it in java so it runs everywhere. Or it could even be like a miniature browser built upon some open-source browser code that only connects to protonmail, so all data is kept on the cloud: no need for data sync.

if this was a thing, id ditch chrome in an instant!

Browsers are very large pieces of software. But perhaps it's possible to make one all about security that lacks some other features like video playback, tabs, history, devtools, addons... All of these things are non-essential.

Definitely a great idea. Does anyone use duckduckgo.com?

Great idea.

We need a browser that TAKES NO POLITICAL SIDE.

I agree that a VPN is not really sufficient to ensure privacy - Google et al still can follow you from crumbs left in your browser etc. The Tor browser is fine but a bit slow ... I think designing a new browser from scratch might be a bit of a resource hog for you tho - maybe joining forces with Vivaldi might make more sense.
In the meantime some guidelines on how to make try and keep as much privacy as possible with the current tools would be welcome.
One way could be to use different browsers or computers for different types of activities .. or another to obfuscate the spying by searching for absolutely anything ... so a randomizer search ..

@ Christopher Dalton - Well stated. I agree wholeheartedly.

4 those who disagree - remember that the NSA is still collecting and storing all data traffic within the U.S. and anywhere else they have tentacles. Remember Edward Snowden?

There are a lot of private browsers out there such as TOR however most of them are slow (yes I know it always will be due to it's privacy browsing functions and ip re routing) I think it's a good idea for protnmail to invest in brwoser idea. The privacy browsers out there are lacking inovation, features , Speed could be improved, most look ugly and some of them is questionable in privacy claims. I think there is a place for proton browser in the market and if they play they cards right it could become a big player in the future.

Wouldn't this end up being somewhat of a parallel of tor?

I would love another browser alternative considering some of the questionable things Mozilla has been doing lately

Firefox Klar is not enough? I would prefer managing PGP certificates, imap and exporting private key

Can't you use private browsing?

absolutely sounds simply amazing a secure browser all for it!

Chrome is not the only browser. There's no need for a ProtonBrowser.

I think a browser would be great like Comodo dragon did with there browsers.

I think Proton Browser would be a great project.
