If You Value Your Online Privacy, Change These Browser Settings ASAP

You can give your online privacy a major boost by taking five minutes to adjust a few settings in Chrome, Safari, Firefox, Edge or Brave.

Privacy is more of a priority than ever for browser developers, but your browser’s default settings still may not be as robust as you’d like in fighting pervasive ad industry trackers. You can take your online privacy into your own hands and outsmart that online tracking, though.

One of the best and easiest ways to start is by adjusting some of your browser settings.

Incidents like Facebook’s Cambridge Analytica scandal in 2018 elevated privacy protection on Silicon Valley’s priority list by revealing how companies compile reams of data as you traverse the internet. Their goal? To build a richly detailed user profile so they can target you with more tailored, clickable and thus profitable advertisements.

Apple and Google are in a war for the web
, with Google pushing aggressively for an interactive web to rival native apps and Apple moving more slowly — partly out of concern new features will worsen security and be annoying to use. Privacy adds another dimension to the competition and to your browser decision.

Apple has made privacy a top priority in all of its products, including its Safari browser. For the Brave browser, privacy is a core goal, and Mozilla and Microsoft are touting privacy as a way to differentiate their browsers from Google Chrome. But despite Google’s reliance on ad revenue, Chrome engineers are working on rolling out a new privacy-preserving ad-targeting technology called Topics, which the tech giant is testing as a replacement to its failed FLOC project.

One quick way to give yourself a privacy boost across all of the browsers listed here is by changing the default search engine. For instance, try the privacy-focused search engine DuckDuckGo. Although its search results may not be quite as useful or deep as Google’s, DuckDuckGo is still pretty close — and it’s long been favored by the privacy-minded for its refusal to track user searches.

Other universal options that can boost your privacy include disabling your browser’s location tracking and search engine autocomplete features, turning off password autofills and regularly deleting your browsing history. If that’s not enough and you want to take your privacy to the next level, consider trying one of the virtual private networks CNET has reviewed that work with all browsers. (You can also check out our roundups of browser-based VPNs to try

In the meantime, though, here are some simple settings you can change in your browser to help keep a good portion of advertising trackers off your trail.

Chrome browser privacy settings to change

The world’s most popular browser is also generally thought to be one of the least private when used straight out of the box. On the plus side, however, Chrome’s flexible and open-source underpinnings have allowed independent developers to release a slew of privacy-focused extensions to shake off trackers.

In the Chrome Web Store, click Extensions on the left and type the name of the extension you’re looking for into the search bar. Once you find the correct extension in the search results, click Add to Chrome. A dialog will pop up explaining which permissions the extension will have for your browser. Click Add extension to bring the extension into your browser.

If you change your mind, you can manage or remove your extensions by opening Chrome and clicking the three-dot More menu on the right. Then select More Tools and then Extensions. From here, you’ll also be able to see more about the extension by clicking Details.

Here are four extensions to look at as you get started: Cookie Autodelete, uBlock Origin, Privacy Badger and HTTPS Everywhere.

If you’re on Android, sorry: extensions don’t work. So you’ll have to switch browsers altogether to something like DuckDuckGo’s app.

In the same three-dot menu in Chrome, you can also block third-party cookies by selecting Settings, then scrolling down to the Privacy and security section and clicking Cookies and other site data. From here, select Block third-party cookies.

There are several other settings to disable in the Privacy and security menu. Here are a few more.

Clear browsing data > Advanced > Select an option under Time range and hit Clear data.

Security > Under Safe Browsing, select Standard protection > toggle off Help improve security on the web for everyone.

Security > Under Advanced, toggle on Always use secure connections

But it’s not that simple. By going back to the Settings menu — or accessing it directly by typing chrome://settings into your address bar — you’ll see an entire list of options on the left, and each of them have privacy-related options to enable or disable. Listing them all would require an article of its own, but here are a few key settings to get you started.

Settings > You and Google > Sync and Google services > toggle on Allow Chrome sign-in. This tells Chrome not to associate your browser activities with your account until you’ve signed into your Google account. While you’re in this screen, toggle off the following:

Autocomplete searches and URLs
Help improve Chrome’s features and performance
Make searches and browsing better

For core privacy, you should turn off all functions under Settings > Autofill. If you’re looking to maintain the convenience of logging into familiar sites, you shouldn’t let Chrome keep your passwords. Instead, choose a password manager like Bitwarden and install its extension in Chrome.

Chrome is also a browser that can access data about what you do outside of it. If you’re a MacOS user, you can restrain some of that data-grabbing by doing two things. First, you can disable IPv6. Then, you can select System Preference under your Apple menu, followed by Security & Privacy.

In this window, click the lock icon in the bottom to begin making changes. Then go through each of the items one at a time on the left-side pane. Every time you select an item and see Chrome among the list of apps appearing in the right-side pane, click Chrome to highlight it and then click the minus-sign icon beneath the pane on the right side to remove Chrome from the list. This is also a great place to see the overwhelming amount of personal data other apps may have access to.

Don’t forget to click the lock icon again to save your choices before exiting the Security & Privacy window.

Safari browser privacy settings to change

By default, Safari turns on its proprietary Intelligent Tracking Prevention tool to keep you a step ahead of privacy pests. Even so, the tool hasn’t always worked smoothly since its 2017 debut. Google researchers spotted how Intelligent Tracking Prevention itself could be used to track users, though Apple buttoned down the problem.

Safari is able to tell you which ad trackers are running on the website you’re visiting and give you a 30-day report of the known trackers it’s identified while you were browsing. It’ll also tell you which websites those trackers came from.

To check that blocking is on, open Safari and click Preferences, then Privacy. The box beside Prevent cross-site tracking should be checked. While you’re there, you can also manually delete your cookies. Click Manage Website Data to see which sites have left their trackers and cookies hanging out in your browser. Click Remove next to any of the individual trackers you’re ready to get rid of, or just nuke the whole list by clicking Remove All at the bottom of your screen.

Cookies can be helpful, not just invasive, but for stronger privacy you can block them altogether — both first-party cookies from the website publisher and third-party cookies from others like advertisers. To do so, check the box beside Block all cookies.

You can also enable the Hide IP address from trackers function from the Privacy menu to keep your IP address hidden from known online trackers. And if you have an iCloud Plus account, you can use Private Relay to hide your IP address from trackers as well as websites.

If you’re still looking for another layer of privacy, you can also install helpful extensions from the App Store like AdBlock Plus or Ghostery Lite for Safari.

Edge browser privacy settings to change

Microsoft’s Edge browser includes some simplified privacy and tracker-blocking options on its Tracker prevention screen. Within Edge, select the three-dot menu icon in the top-right corner and select Settings. From the menu that then appears on the left, select Privacy and services.

You’ll be offered three settings to choose from: Basic, Balanced and Strict. By default, Edge uses the Balanced setting, which blocks trackers from sites you haven’t visited while still being lenient enough to save most sites from some of the loading problems that may come with tighter security. Likewise, Edge’s Strict setting may interfere with how some sites behave, but will block the greatest number of trackers. Even the Basic setting will still block trackers used for crypto mining and fingerprinting.

Depending on your settings, Edge may send your browsing history and diagnostic data to Microsoft. If you want to prevent that from happening, you can go to Privacy, search, and services from the Settings menu and disable Help improve Microsoft products by sending optional diagnostic data about how you use the browser, websites you visit, and crash reports.

Firefox browser privacy settings to change

Firefox’s default privacy settings are more protective than those of Chrome and Edge, and the browser has more privacy options under the hood, too.

From inside Firefox’s main menu — or from inside the three-lined menu on the right side of the toolbar — select Settings. Once the Settings window opens, click Privacy & Security. From here, you’ll be able to choose between three options: Standard, Strict and Custom. Standard, the default Firefox setting, blocks trackers in private windows, third-party tracking cookies and crypto miners. The Strict setting may break a few websites, but it blocks everything blocked in Standard mode, plus fingerprints and trackers in all windows. Custom is worth exploring for those who want to fine-tune how trackers are being blocked.

To apply your new tracking settings after you’ve selected your level of privacy, click the Reload All Tabs button that appears.

From the Privacy & Security menu, you can also tell Firefox to send a «Do Not Track» signal to websites to let them know you don’t want to be tracked. You can set this to Always or Only when Firefox is set to block known trackers.

Brave browser privacy settings to change

When it comes to anti-tracking tools, Safari’s latest privacy updates are still short of most of those found in the Brave browser
. By default, Brave blocks all ads, trackers, third-party cookies and fingerprinters while still achieving blazing speeds
. Brave also offers a built-in Tor private browsing mode, a heavy-duty tracker-blocking option, and added a built-in VPN for iOS users.

Inside Brave’s main menu, select Settings and then select Shields to see a list of things you can block, like trackers, ads, scripts and fingerprinting. You can set the Trackers and ads blocking to Standard or Aggressive, and you can set the Block fingerprinting function to Standard or Strict. You’ll also be able to block login buttons and embedded content from Facebook, Twitter, Google and LinkedIn from the Social media blocking tab in your Settings menu. For even more protection and privacy fine-tuning, explore the Privacy and security menu.

Apple, I’m (Sky) Blue About Your iPhone 17 Air Color

Commentary: The rumored new hue of the iPhone 17 Air is more sky blah than sky blue.

I can’t help but feel blue about the latest rumor that Apple’s forthcoming iPhone 17 Air will take flight in a subtle, light-hued color called sky blue.

Sky blue isn’t a new color for Apple. It’s the featured shade of the current M4 MacBook Air, a shimmer of cerulean so subtle as to almost be missed. It’s silver left too close to an aquarium; silver that secretly likes to think it’s blue but doesn’t want everyone else to notice.

Do Apple employees get to go outside and see a real blue sky? It’s actually vivid, you can check for yourself. Perhaps the muted sky blue color reflects a Bay Area late winter/early spring frequent layer of clouds like we typically see here in Seattle.

«Who cares?» you might find yourself saying. «Everyone gets a case anyway.» I hear you and everyone else who’s told me that. But design-focused Apple is as obsessive about colors as they are about making their devices thinner. And I wonder if their heads are in the clouds about which hues adorn their pro products.

Making the case for a caseless color iPhone

I’m more invested in this conversation than most — I’m one of those freaks who doesn’t wrap my phone in a case. I find cases bulky and superfluous, and I like to be able to see Apple’s design work. Also, true story, I’ve broken my iPhone screen only twice: First when it was in a «bumper» that Apple sent free in response to the iPhone 4 you’re-holding-it-wrong Antennagate fiasco, and second when trying to take long exposure starry night photos using what I didn’t realize was a broken tripod mount. My one-week-old iPhone 13 Pro slipped sideways and landed screen-first on a pointy rock. A case wouldn’t have saved it.

My current model is an iPhone 16 Pro in black titanium — which I know seems like avoiding color entirely — but previously I’ve gone for colors like blue titanium and deep purple. I wanted to like deep purple the most but it came across as, in the words of Patrick Holland in his iPhone 14 Pro review, «a drab shade of gray or like Grimace purple,» depending on the light.

Pros can be bold, too

Maybe the issue is too many soft blues. Since the iPhone Pro age began with the iPhone 11 Pro, we’ve seen variations like blue titanium (iPhone 15 Pro), sierra blue (iPhone 13 Pro) and pacific blue (iPhone 12 Pro).

Pacific blue is the boldest of the bunch, if by bold you mean dark enough to discern from silver, but it’s also close enough to that year’s graphite color that seeing blue depends on the surrounding lighting. By comparison, the blue (just «blue») color of the iPhone 12 was unmistakably bright blue.

In fact, the non-Pro lines have embraced vibrant colors. It’s as if Apple is equating «pro» with «sophisticated,» as in «A real pro would never brandish something this garish.» I see this in the camera world all the time: If it’s not all-black, it’s not a «serious» camera.

And yet I know lots of pros who are not sophisticated — proudly so. People choose colors to express themselves, so forcing that idea of professionalism through color feels needlessly restrictive. A bright pink iPhone 16 might make you smile every time you pick it up but then frown because it doesn’t have a telephoto camera.

Color is also important because it can sway a purchase decision. «I would buy a sky blue iPhone yesterday,» my colleague Gael Cooper texted after the first rumor popped online. When each new generation of iPhones arrive, less technically different than the one before, a color you fall in love with can push you into trading in your perfectly-capable model for a new one.

And lest you think Apple should just stick with black and white for its professional phones: Do you mean black, jet black, space black, midnight black, black titanium, graphite or space gray? At least the lighter end of the spectrum has stuck to just white, white titanium and silver over the years.

Apple never got ahead by being beige

I’m sure Apple has reams of studies and customer feedback that support which colors make it to production each year. Like I said, Apple’s designers are obsessive (in a good way). And I must remind myself that a sky blue iPhone 17 Air is a rumored color on a rumored product so all the usual caveats apply.

But we’re talking about Apple here. The scrappy startup that spent more than any other company on business cards at the time because each one included the old six-color Apple logo. The company that not only shaped the first iMac like a tipped-over gumdrop, that not only made the case partially see-through but then made that cover brilliant Bondi blue.

Embrace the iPhone colors, Apple.

If that makes you nervous, don’t worry: Most people will put a case on it anyway.

Astronomers Say There’s an Increased Possibility of Life on This Distant Planet

Using the James Webb Space Telescope, astronomers are working to confirm potential evidence of life on a distant exoplanet dubbed K2-18b.

Astronomers are nearing a statistically significant finding that could confirm the potential signs of life detected on the distant exoplanet K2-18b are no accident.

The team of astronomers, led by the University of Cambridge, used data from the James Webb Space Telescope (which has only been in use since the end of 2021) to detect chemical traces of dimethyl sulfide (DMS) and/or dimethyl disulfide (DMDS), which they say can only be produced by life such as phytoplankton in the sea.

According to the university, «the results are the strongest evidence yet that life may exist on a planet outside our solar system.»

The findings were published this week in the Astrophysical Journal Letters and point to the possibility of an ocean on this planet’s surface, which scientists have been hoping to discover for years. In the abstract for the paper, the team says, «The possibility of hycean worlds, with planet-wide oceans and H2-rich atmospheres, significantly expands and accelerates the search for habitable environments elsewhere.»

Not everyone agrees, however, that what the team found proves there’s life on the exoplanet.

Science writer and OpenMind Magazine founder Corey S. Powell posted about the findings on Bluesky, writing, «The potential discovery of alien life is so enticing that it drags even reputable outlets into running naive or outright misleading stories.» He added, «Here we go again with planet K2-18b.Um….there’s strong evidence of non-biological sources of the molecule DMS.»

K2-18b is 124 light-years away and much larger than Earth (more than eight times our mass), but smaller than Neptune. The search for signs of even basic life on a planet like this increases the chances that there are more planets like Earth that may be inhabitable, with temperatures and atmospheres that could sustain human-like lifeforms. The team behind the paper hopes that more study with the James Webb Space Telescope will help confirm their initial findings.

More research to do on finding life on K2-18b

The exoplanet K2-18b is not the only place where scientists are exploring the possibility of life, and this research is still an early step in the process, said Christopher Glein, a geochemist, planetary researcher and lead scientist at San Antonio’s Southwest Research Institute. Excitement over the significance of the research, he said, should be tempered.

«We need to be careful here,» Glein said. «It appears that there is something in the data that can’t be explained, and DMS/DMDS can provide an explanation. But this detection is stretching the limits of JWST’s capabilities.»

Glein added, «Further work is needed to test whether these molecules are actually present. We also need complementary research assessing the abiotic background on K2-18b and similar planets. That is, the chemistry that can occur in the absence of life in this potentially exotic environment. We might be seeing evidence of some cool chemistry rather than life.»

The TRAPPIST-1 planets, he said, are being researched as potentially habitable, as is LHS 1140b, which he said «is another astrobiologically significant exoplanet, which might be a massive ocean world.»

As for K2-18b, Glein said many more tests need to be performed before there’s consensus on life existing on it.

«Finding evidence of life is like prosecuting a case in the courtroom,» Glein said. «Multiple independent lines of evidence are needed to convince the jury, in this case the worldwide scientific community.» He added, «If this finding holds up, then that’s Step 1.»
