Forking, or acquiring, the LibreWolf browser would be a smart move. Most of the work to make it private has already been done (it is considered the most private browser behind Tor Browser).

The only work that would be required would be an overhaul of the UI to make it consistent with the Proton suite of apps and integration of Proton services.

The only thing I would want to see personally is vertical tabs similar to the Arc browser implementation.

To all the naysayers I say, Chromium is open source. Yes, it's provided by Google, but it's still open source. The browser is already built. Proton would only be creating the secure configuration that all the other browsers lie about. If Proton did it, we'd know they'd have our best interests in mind and that would not change over time. And they do not need to do it at the exclusion of their other apps. They can do it as they can do it. We're just asking the put it on the road map. And judging by the support, it's a very popular request. Isn't that exactly what this site is for?

I must confess to finding the amount of support for a Proton browser here quite disturbing, and even more so the level if support in Proton's recent user survey. I can only hope that Proton does not follow this through in any way, shape, or form, i.e., that sanity prevails. Implementing a web browser, whether a fork from extant examples or creating one from scratch, would be the most colossal waste of Proton's not limitless resources if not utter insanity.

Proton needs to consolidate its existing apps, eliminate any bugs and minor issues in them and gradually improve them. That takes considerable resources, both in terms of coding manpower and finance, resources that could and certainly should not be squandered on populist wet dreams such as a Proton browser or search engine.

There are already more than enough alternative, privacy-focused browsers - and for that matter, search engines - around that are all struggling to get a decent slice of the user base pie.

In addition to consolidation, there certainly are considerably more important and suitable apps that Proton could implement to expand the ecosystem.

Call me a cynic, but IMO the popular vote has never resulted in anything sensible in almost any field - 'nuff said!

since there's many high risk "add blocker extension" already available but if its from proton and with Proton browser then Thunderstorm!! 💯🙌🎩

Since Proton Mail is encrypted I personally think that Proton should make a Browser with a built-in Proton VPN, Proton Pass, Adblocker etc (Always on) for Windows, Mac, IPhones, Android etc. That way the users can be safe when searching but also safe from malicious advertising

I wish Proton would make a Privacy browser based on Chromium.

As, I am not a fan of Brave with all their unnecessary bloatware that is included and turned on by default.

It would be awesome to have a browser that prioritize privacy, security and is connected with Proton ecosystem.

It could have features like:

1.) Encrypted stored cookies,

2.) Isolated processes,

3.) Cookies that delete when a website domain is closed similar to brave's "forget me when I close this site",

4.) Encrypt the entire browser when the browser is closed.

5.) ECH (Encrypted Client Hello) for DNS,

6.) Encrypted Local Browsing History,

7.) Encrypted Cache,

8.) Feature similar to Total Cookies Protection by Firefox,

9.)Built in AD, Tracker, and Malware Domain blocker (where Proton has their own Blocklist, but you the user can add your own and add additional Blocklists that are provided like how NextDNS does Blocklists) also with functionality like uBlock Origin but natively built in,

10.) Passkey support,

11.) Security Key Authentication (Yubikey) to open the browser from a closed state of enable,

12.) HTTPS Only Mode,

13.) Permanent Private Browsing Mode,

14.) Extensions on Android,

15.) Sign in with Proton Account to sync Browsing History, Emails, Proton Pass passwords, etc, Also a sync feature similar to Brave if the user doesn't want to sign in with Proton to sync settings,

16.) Native containers like the Firefox Extension,

17.) Browser Profiles,

18.) Site permission page where you can where you disable certain settings (As with Brave if you disable shields on a website, Brave will not let you have a menu to see which sites have what permissions revoked or edited),

19.) Disable WebRTC by default or through an on screen set up page when you first download the browser,

20.) Advanced Fingerprinting protections,

21.) A Secure mode option where it turns off JIT JavaScript and other security settings that can cause exploits similar to lockdown mode for Apple devices,

22.) Cookies deletes on browser close,

23.) A Cookies do not delete list,

That is all I can think about for features. If chrome doesn't already have some of these implemented already in their source code.

...or at least a cleaned up Firefox fork.

Might also be nice if they take inspiration from the arc browser

There is a browser for every need in the market right now. I don't think proton can come up with something unheard of

This seems like a waste of resources, similar to ProtonPass. We already have browers that work perfect. I would rather Proton spend time making what they have already implemented better.

I agree with some other people from the comments.

This would be a very bad use of resources at Proton. Developing a browser from scratch takes enormous efforts and an extended period of time.

Instead, a browser add-on, build on already existing Open source projects (like uBlock Origin) might do the trick. Maybe something allowing for a Librewolf like experience (in terms of privacy and security tweaks) on Firefox or Chrome based browsers as an add-on.
But honestly, it can likely already be archived through existing extensions.

I quite disagree. Two ways of doing it: creating a new web browser from scratch, or taking one of them and adding a Proton layout. The first one is too time consumming regarding other priorities, even if I agree that it's a shame that Chromium is everwhere, and that Firefox is the only "mainstream" alternative. The second, I don't see what I would gain that a simple extension couldn't provide.

A Proton browser would be very useful,
but it would take time and resources.

It would definitely be possible,
but it would take time until Proton presents a browser.

A browser would take around 3-5 years if Proton were to develop one,
because the browser needs a lot of security features and at the same time has to be fast.

But let's wait and see.

I do not support this idea. I think the Tor Browser and Mullvad Browser do a great job already. A browser would add more work to a whole different thing than the main products. Rather than breath, Proton should focus on the depth of its products.
There still are countless "basic" features in Mail, Drive, and Calendar that could be implemented, and I think it makes more sense to put resources into them rather than making and maintaining a web browser and/or a search engine.

Mullvad Browser really did a great job already. I'd love you see team up with The Tor Project & Mullvad however to make it even better.

I would greatly appreciate a proton browser! Plus it would help spread the word about proton.

Most other web browsers allow vulnerabilities and target us with ads.
Firefox used to be pretty good, but the quality and performance lately has declined. We need something better. True boolean search would be a great addition, including search within results.

Like someone else has already stated, it would be absolutely great to add our own Proton Browser to the Proton environment (please, withhold judgment until you've read the last paragraph). It feels like the one thing that is missing (however, I do wish Proton would make a Virtual Card service for online payments as well.) I am making a separate post to share my thoughts more clearly and to be notified about any feedback.

- Search Engine
Proton is more than capable of creating its own privacy-focused search engine. That being said, when it comes to online searches, I like to get as many results as I can, that's why I use SearXNG on hardened Firefox which combines the results of multiple search engines. It would be great to have something like that. However, it would also make sense to have something unique to proton, akin to what Brave was trying to do. The only difference being that Brave relies on Chromium - something I would NOT enjoy for Proton's browser.

- Extensions
Needles to say, the browser should support extensions for the other Proton apps, notably Pass and VPN.

- Price
To make this more appealing, there could either be a free version of this with heavy limitations, or make it an exclusive feature for Plus / Unlimited users. I can see that there could even be a new plan just for the browser, like there are for Pass, Mail, VPN.

- Safety
It would be nice, though not essential, to have some sort of integrated antivirus / antitracker with Proton Sentinel. Perhaps another extension? The idea is that when downloading a harmful file, or trying to reach a dangerous site, Proton Sentinel (or anything akin to that) will warn you and try to prevent you from doing that.

- Quality over quantity
This can potentially draw too many resources from the company and its workers. While having a dedicated browser sounds very appealing to some - and to me - there is the harsh reality that such a project could distract Proton from managing and improving the already existing apps. That is not something the userbase would appreciate. A Proton-made version of Firefox sounds good, too, but it might be redundant with the absurdly vast amount of other options there are currently. In my case, Librewolf for PC and Mull for Android. Would Proton's browser be able to compete? I can only see it possible if it actually ended up not being free, or maybe it would simply be just not a smart business move.
