How Deleting Your Android Web Browser’s Cookies and Cache Keeps Junk Out of Your Phone

It’s hard to tell how many tracking cookies are in your phone’s web browser, so it’s best to wipe them out every so often.

Your Android phone‘s web browser may be filled with tons of data, including files you don’t need to keep. Much of that data — whether you’re using Google Chrome, Firefox or Samsung Internet — gets stored as part of the cookies and cache. This data can be helpful for websites you visit, letting them load faster with your accounts already logged in. That’s nice, but there’s plenty of information in the cookies and cache of your browser that isn’t necessary and could even be a privacy risk.

Why you should regularly clear out your cookies and cache

A lot of what ends up building up within your cookies and cache is just plain junk. Some of it could have arrived from websites you’ve visited just once. Others seem to be tracking your browsing history on an active basis, helping to serve up advertisements based on what you are buying or streaming on the internet. For instance, I’m constantly receiving advertisements for buying glasses online after browsing a few stores, or Amazon ads that just happen to show what was last in my shopping cart.

Because of this, it’s good to clear out your cache every so often. It allows you to remove data you don’t need on your phone, especially if an unknown data tracker is among your phone’s cookies. Clearing your cache is a minor inconvenience — you’ll have to log back into some of your favorite websites, but it’s a small price to pay to make sure your phone isn’t stocking up on extraneous data.

The steps differ slightly depending on the type of phone and web browser app you’re using. Below, we’ll go over how to clear this data for Google’s Chrome browser (often the default for many Android phones, like the Google Pixel line), Samsung’s internet browser (often the default on the Galaxy phone series) and Mozilla’s Firefox browser. You can also check out our separate guide on how to clear your cache on an iPhone web browser, in case you have a few Apple devices to tidy up, too.

Google Chrome

You can delete your cookies and cache from within the Android version of Google Chrome by first tapping the More button in the top right corner of the browser, indicated by a column of three dots, then tapping History, then Clear browsing data. You can also access this from the Chrome Settings menu, tapping Privacy and Security and then Clear browsing data.

Chrome also offers Basic and Advanced settings for clearing your Browsing history, Cookies and site data and Cached images and files. You can use the Time range drop-down to select whether you want to delete the entire history or a selection of anywhere from the past 24 hours up to the last four weeks. Tapping Advanced will also give you access to deleting Saved passwords, Autofill form data and Site settings. After selecting what you want to delete, tap the blue Clear data button. You might receive an additional prompt in the event Chrome deems certain websites as being «important» to you, and if so you’ll get the chance to confirm before clearing. Otherwise if you do not receive that prompt, Chrome will immediately proceed to clear as you instructed.

Samsung Internet

There are two different ways you can clear your Samsung Internet browser’s cache and cookie data. You can clear from within the browser itself, or you can go through your phone’s Settings app.

To clear while in the Samsung Internet browser app, first tap the Options button in the bottom right corner represented by three horizontal lines, then Settings; scroll down to and tap Personal Data, then tap Delete browsing data to get a menu of options to delete. You can clear your Browsing history, Cookies and site data, Cached images and files, Passwords and Autofill forms in any combination. After tapping Delete data, you’ll then receive a prompt asking for you to confirm your choices before deleting.

Going through the browser app itself provides the most customization of what you want to delete. However, if you want to access similar options from your phone’s settings menu, open the Settings app and tap on Apps, then scroll down to and tap Samsung Internet and then Storage.

At the bottom of Storage, you get separate options to Clear cache and Clear data. Tapping Clear cache will immediately delete the cache, but Clear data brings up a prompt that warns you that all of the application’s data will be deleted permanently, including files, settings, accounts and databases. While it doesn’t specify cookies, this «going nuclear» approach should zap all remaining data, letting you restart the Samsung Internet browser as if it were brand-new.

Mozilla Firefox

Much as with Google Chrome, you can clear the cache from within the Mozilla Firefox Android app. To access this function, tap the More button on the right of the address bar, again symbolized by three vertically aligned dots. Then tap Settings and scroll down to Delete browsing data.

Of the three browsers we’re discussing here, Firefox gives you the most options under the Delete browsing data menu, allowing you to also delete any existing Open tabs, your Browsing history and site data, Site permissions and even your Downloads folder alongside Cookies and Cached images and files.

While you can’t pick a time range as you can for Chrome, you can be more specific regarding what type of data you would like to remove.

And Firefox has an additional option for those who never want to keep their browsing data after they’re done using the app. Inside of Settings is a Delete browsing data on quit option, which instructs Firefox to wipe any combination of these same settings every time you quit the application. It’s a useful feature if you’d like to keep the browser tidy and, say, avoid accidentally handing off your browser history to someone who may have stolen or otherwise gained access to your phone.

Google, Meta and Amazon Join Global Pact to Fight Rising Online Scams

The companies will share fraud intelligence and coordinate responses as AI makes scams faster, cheaper and harder to detect.

Modern online scams operate across multiple platforms, perhaps spanning social media, messaging apps, email and online marketplaces. Google, Meta and Amazon are among 11 tech, retail and payments companies that have signed a new agreement to combat online scams by sharing threat intelligence across platforms, Axios first reported Monday.

The initiative, called the Industry Accord Against Online Scams & Fraud, is designed to improve how companies detect and respond to fraud that spans multiple services. Participants say they will exchange signals, such as scam-linked accounts and fraudulent domains, and coordinate enforcement actions.

By sharing intelligence in near real time, companies hope to identify these scams earlier and stop them before they spread.

The effort reflects how modern scams operate. A victim might encounter a fake celebrity investment ad on social media, move to a messaging app where the scammer builds trust, then faces prompts to send money through a fraudulent website, payment app or crypto wallet — spanning multiple companies’ ecosystems.

Google said it now blocks hundreds of millions of scam-related results every day using AI, underscoring how both attackers and defenders are increasingly relying on the same technology. Meta removed more than 159 million scam ads in 2025 and is expanding AI tools to detect impersonation and warn users.

Online scams are growing rapidly, in part because generative AI has lowered the barrier to entry. AI can be used not only to produce realistic phishing emails but also to clone voices and deepfake videos that impersonate executives, public figures and even family members.

The agreement is voluntary and doesn’t create new legal obligations, but it comes after regulators’ increased pressure on tech platforms to address fraud more aggressively. The companies say they will begin building frameworks for reporting and intelligence-sharing, though it’s not yet clear how quickly those systems will be deployed or how effective they will be in practice.

Amazon Speeds Up Delivery Even More With 1- and 3-Hour Options

The retailer says the one-hour option is available in hundreds of cities, with discounted shipping for Prime members.

Same-day delivery apparently isn’t fast enough for some Amazon shoppers. The retail giant said on Tuesday it’s adding new shipping options that will get products to front doors within a one- or three-hour window.

The company said in its announcement that the one-hour option is available in hundreds of cities across the US, while the three-hour option is now live in more than 2,000 areas. Amazon’s web page at amazon.com/getitfast shows whether those options are available to shoppers for their location. More than 90,000 products will be available for those shipping windows, the company said.

For those who can’t get those services (including the author of this post, who lives between Austin and San Antonio in Texas), a message will display: «3-hour delivery is currently unavailable. Check back at a later time or shop products with Same-Day delivery below.»

Pricing for the faster delivery options is not cheap: It’ll cost you $20 for one-hour delivery and $15 for three-hour delivery for those without an Amazon Prime account, or $10 and $5 for customers who subscribe to Prime.

Last year, the company rolled out faster Amazon delivery options to 4,000 additional areas.

In a video of the podcast Learn and Be Curious with Doug Herrington, hosted by Amazon’s CEO of worldwide stores, Kandace Kapps, the director of the company’s same-day strategy team, spoke in more detail about the challenges of fast shipping. Kapps discussed shifts in customer buying habits over the last few years, such as more people buying household essentials like toilet paper on Amazon.

She said that Amazon can deliver so quickly by placing same-day delivery hubs close to customers in metro areas and by getting products ready to ship within 15 minutes, aided by warehouse robots.

«I think customers are going to continue to get magically surprised by how fast we can deliver to their doorstop,» Kapps said.

Herrington said fast shipping increases sales: «When we speed up the service, the probability that somebody buys a product from us goes up.»

Other retailers, including Walmart, have been adding same-day delivery options or exploring other ways to speed up shipping times to compete with Amazon.

Removing buyers’ moments of hesitation

Part of Amazon’s strategy, which has involved a massive buildout of locations, deployment of thousands of trucks, deals with other delivery services and investment in logistics software, is actually pretty simple: being there when people need last-minute items or make impulse buys.

«It’s about removing the last moment where you would’ve reconsidered the purchase,» said Stephanie Carls, retail insights expert at coupon and promotional-code website RetailMeNot, a sibling site of CNET. «It changes how you shop, not just how fast you get things.»

Carls said that Amazon’s super-fast delivery is removing the timeframe when people might change their minds about a purchase.

«There used to be a gap between deciding to buy something and actually having it. That’s when you’d price check, rethink it, or decide you didn’t need it after all,» she said. «This closes that gap.»

The retail expert said that competitors, including Walmart and Target, have been speeding up delivery times in some markets. Still, they’re not matching Amazon’s scale or product range at those speeds or levels of consistency.

«And that’s what starts to make everyone else feel slow,» Carls said. «Amazon’s advantage is how tightly connected its technology, inventory and delivery networks are, which makes this level of speed more repeatable.»
