This is useful to use as your default browser. It has a quick way to open the same link in another browser, so you can use it as a sort of quarantine to vet unknown links before exposing your main browser and all its juicy user data to a new website.

or just install Firefox with noScript. (until we get umatrix to work on fennec)

remove the rule that allows script from the original domain. done. now all sites will be quarantine, until you white list them.

>Maybe I'm missing something. The features you explained are exactly what I was looking for in a mobile browser. In fact, i wish they launch Focus for Desktops operating systems too.

I think you're looking for the Tor Browser. If you don't log in into websites, I don't see why you would leave yourself exposed and very easily hacked with Firefox or private browsing if there's Tor. Private browsing is NOT secure. It's just a shortcut to avoid clearing your history manually. ANYONE can see who you are, and what sites you visit with easy-to-use tools that are available online for free.

> Private browsing is NOT secure.

Security is not an absolute. The best you can do is talk about whether something addresses a particular threat model.

There are different tradeoffs to Tor. A big downside is that unencrypted traffic is now easier for intermediaries to read and even change, because of how exit nodes work.

Tor (not Torbrowser) is very different from incognito/private browsing. Even for your own use, it's another layer of defense to reduce the storage of information on the device about whatever you've been up to. Certainly porn is not the o…

If you think incognito mode protects you in any way, than it's you who is naive. If anyone really wanted to track you, they can use your IP and see every single page you've visited. Even the size of your window is enough to track you. Tor is the…

Sorry, it seems like you didn't read my post fully or get it. I described that incognito/private browsing mode is one layer of defense, not the only layer. I also provided examples of your device being borrowed by someone else or it being stolen. In those cases, whether you used Tor (not Torbrowser, which I explicitly excluded even in my previous comment) doesn't matter. Whatever your browser has stored on the device - including browsing history, cache, cookies - is available to them to use or sell to others.

Also, I didn't mention the government as the sole hostile entity in my comment. One's own employer may use information in your browser cache on an employer provided device to fire the person or even file a criminal lawsuit against the person. Some malicious program a person downloaded may scrape all information from your caches and send that to insurers or other "data brokers" who in turn would classify you as too high a risk to support. There are far too many possibilities here that I cannot list every single one of them.

As for those who post pictures on social media about being drunk, posting racist messages, etc., that's really bad in many ways, but such protections and more should also start with each of us individually. It's in that space that I see using icognito/private browsing mode as one more helpful layer. Tor is another layer. Encrypting one's devices' storage is another. And so on.

Focus (for Android) doesn't use Google analytics directly, but it's an indirect dependency - see below. Focus does have: - Mozilla telemetry: enabled by default in Focus, disabled by default in Klar. This only sends data to Mozilla servers, and only concerns what features people use (i.e. do people use share, do people use custom tabs, do people clear using the bin button or the notification). This stuff is used for…

This stuff is used for deciding what features to prioritise This is exactly what every company tells you why they collect data. "To serve you better ...". The hypocrisy to advertise "tracking protection" as a key feature and then send tracking data to your own servers is hillarious.

I'll add an anecdote as a counter-example (I think the details might be a bit off here, it might not be VS):

Visual Studio removed 'macro' functionality, and a bunch of developers went to the forums to complain and demand an explanation.

That explanation was as follows: None of those developers enabled "send usage feedback," so the usage statistics for macros was close to 0%. The developers sensibly thought it made sense to stop supporting that feature.

There's a tradeoff associated with extreme privacy, and perfect is the enemy of good.

You can't advertise as a "private browser" an get away with that PR bullshit. "Anonymous" usage data is anything but when the server receiving it can easily tell who it's coming from. Mozilla is not the user, it breaks the entire idea of privacy.

If you don't trust Mozilla, you shouldn't use their browser at all regardless of what packages it imports. I think you're being a little silly though.

I don't have to trust them if the code is open source and it doesn't send any data back to them or anyone else unless I explicitly allow it. I will try this browser and I will turn off telemetry, just like I do with Firefox. What makes me angry is why call it a "private browser" and not take it all the way? You can accomplish everything this browser does with Firefox except you have to configure it, why leave this one last thing enabled by default? I know no one at Mozilla really thinks "you can trust us" is a valid claim in the privacy game so something else is up, probably not a conspiracy, but at the very least, the wrong people are making some calls.

Probably a mix of Apple not having a monopoly in the mobile space and other browsers till being allowed on the app store.

I am not up to date. I didn't realize they allow other browsers now. When I was building iOS apps Apple had specific wording which prevented apps in the app store which duplicated functionality already available in iOS. That meant things like the AdBlock Firefox build could not be published in the App Store. It was, in great part, their legal team and strategy that pushed me away from Apple.

Apple still doesn't allow true browsers in the app store. Not because they disallow duplicate system applications (plenty of calculator apps out there). The problem is that Apple does not allow any developer to use a browser engine other than built-in Safari. Apple also doesn't allow virtual machines/on the fly compilation of code, making any alternate, fast enough Javascript engine practically impossible.

"Browsers" on iOS, such as Firefox Focus and Chrome, just repurpose the built-in Safari engine with some modifications (bookmark sync, extra content blocking, etc.)

I wouldn't consider tabs 'every beta bell and whistle' :-/ If you can live without tabs, try it, it's great.

Focus was initially intended for users who are concerned about privacy, but in no way short of helpless in actually trying to get it. The type of user that has trouble finding or even understanding Private Browsing in Firefox. (Focus does not actually protect privacy more than Firefox's Private Browsing mode either.) Launching a separate app on the other hand is a familiar concept and does also explain quite nicely t…

Thanks for the background information, I am looking forward to Focus 3.0 now :-)

The biggest problem with this line of thinking is telemetry data _can_ be used extremely effectively to "serve you better". Denying the ability to collect telemetry data for privacy conscious products is to deny them the ability to improve their products using data-driven approaches that have been proven to be overwhelmingly effective in practice. This would be an extremely heavy handicap, and could very easily make…
