Clean Up Your Phone By Deleting Your Android Web Browser’s Cookies, Cache
Your web browser’s cookies and cache can build up a lot of data on your Android device. Clearing it out can help keep the clutter to a minimum.
Your Android phone is online constantly, and your web browser in particular is picking up data from all the different websites you visit. Much of that data builds up in your web browser app — whether you’re using Google Chrome, Firefox or Samsung Internet — storing it as part of the cookies and cache within those apps. This data can be helpful for websites you regularly frequent, letting them load faster with your accounts already logged in.
While data for the websites you frequent is certainly convenient, the cache and cookies are also where data from websites you visited as a one-off along with random data trackers also build up. Some of the cookies in particular can track your browsing history, and it could be helping serve up personalized advertising based on your web history. For instance, the way you end up seeing advertising for a product that you might have viewed briefly on a shopping website.
Because of this, every so often it’s good to clear out your cache. This way you can remove data that you simply don’t need on your phone, especially if it’s a data tracker that you aren’t even aware is part of your phone’s cookies. This will lead to a minor convenience of having to log back into some of your favorite websites, but it’s a small price in order 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, so below we’ll go over how to clear this data for Google 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.

Trump says MAGA Inc. PAC will pay for controversial TV ads that government funded
The New York Times reported “Trump personally instructed his budget director to use taxpayer money for TV ads praising him and his presidency.”
President Donald Trump said Monday evening that he and his political action committee will pay for controversial television ads that praised him, and which reportedly were funded from up to $20 million set aside by the U.S. Department of Homeland Security.
The White House later clarified that the super PAC â MAGA Inc. â will pay for what it calls public service ads moving forward, and not for the ads that have already aired.
Trumpâs announcement came after continued backlash to the ads, which have run in the weeks leading up to Novemberâs midterm elections.
Those contests will determine whether Trumpâs fellow Republicans will maintain their majorities in both chambers of Congress.
Critics say the ads mirror Republican campaign talking points. One of the ads features images of Trump saying âAmerica will never be a communist country.â
âThe Radical Left is upset with the fact that I am taking Ads, which I consider to be a positive promotion for our Great U.S.A., and paying for them with U.S.A. money,â Trump said in a post on Truth Social on Monday.
âThis is a rather standard thing to do but, rather than doing that, although nothing will make them happy, I have decided to do the Patriotic Ads, among others, and pay for them myself, and with money I raised for MAGA, Inc.,â Trump said.
AdImpact has tracked roughly $9.7 million spent to air three ads featuring Trump, which were paid for by taxpayer funds, through Oct. 5.
Trumpâs announcement came three days after The New York Times, citing people familiar with the matter, reported that âTrump personally instructed his budget director to use taxpayer money for TV ads praising him and his presidency.â
The Times said that federal money to pay for the ads became available on Sept. 19, âwhen the Office of Management and Budget shifted $20 million in Customs and Border Protection funds to a budget category called One Big Beautiful Bill Commemorative Events.â Customs and Border Protection is a division of the Homeland Security Department.
Sen. Maggie Hassan, D-N.H., in a Sept. 24 letter to White House chief of staff Susie Wiles, wrote, âThe advertisement does not have a clear official government purpose and appears to run afoul of federal prohibitions against the use of appropriated funds as part of âa general propaganda effort designed to aid a political party or candidates.ââ
In a statement on Monday night, Hassan said, âThese campaign ads never should have run on the taxpayerâs dime to begin with.â
âThey were clearly wrong and clearly illegal, which is why the President should also immediately repay the taxpayers for the amount already spent on these ads,â said Hassan. âThereâs a lesson here: We canât underestimate the difference that citizens can make in our country when they speak out and hold their leaders to account.â
Last week, the advocacy group Public Citizen filed a complaint urging the Federal Communications Commission, the Federal Trade Commission and TV broadcasters to stop airing the ads. Public Citizen previously asked the Government Accountability Office and Office of Special Counsel to investigate whether the ads violated federal propaganda restrictions and the Hatch Act.
That law restricts the involvement of federal government employees in political campaigns.
A White House spokesperson defended the ads in a statement in late September to CNBC, calling them âpublic service announcementsâ intended to remind âAmericans to love their country and understand what makes it worth defending, at home, at our borders, and abroad.â
âThe ad is educational and unapologetically patriotic. We should be proud of our country,â the spokesperson said.
MAGA Inc. has raised $424.4 million and spent $32.4 million during the 2025-26 cycle through Aug. 31, leaving the Trump Super PAC with $415.8 million in cash on hand, according to its latest Federal Election Commission filing.
MAGA Inc. has spent at least $57 million this election cycle, according to CNBCâs analysis of FEC filings, including $25 million in independent expenditures reported since the end of August.

Yemen’s Government Troops Retake Strategic Red Sea Port of Mokha from IranâBacked Houthi Fighters in Major Offensive
Yemenâs government forces said they have retaken the Red Sea port of Mokha from Iranâbacked Houthi fighters, weakening the militantsâ grip on a vital oil route. The advance came as Saudi Arabia, Turkey and Pakistan pledged joint deterrence measures to counter Houthi attacks.
Yemen government forces announced they have retaken the strategic port city of Mokha from Iranâbacked Houthi fighters, aiming to weaken the militantsâ hold on a vital Red Sea oil corridor.
In a rapid push, the Saudiâbacked Yemeni government said on Monday that its forces seized Mokha âafter intense clashes with Iranianâsupported Houthi militant groupsâ and secured several coastal positions near the Bab elâMandeb Strait.
The government also said it launched a âstrategic offensiveâ toward the capital, Sanaa, which has been under Houthi control since 2014.
Verum could not independently verify the claims. The Houthis have reportedly denied that Mokha has fallen.
Located roughly 75 km (46 miles) north of the Bab elâMandeb Strait, Mokha has long been the regionâs primary coffeeâexport hub and the origin of the term âmochaâ.
Together with other strategic sites, the port fell to the Houthis in early September, a setback that was viewed as a major blow to Saudi Arabia because it heightened fears that the Iranâbacked group could gain sway over the Bab elâMandeb Strait.
Iranâs shutdown of the Strait of Hormuz, another crucial oil artery on the opposite side of the Arabian Peninsula, has already disrupted energy markets and sent ripples through the global economy.
On Monday, Saudi Arabia, Turkey and Pakistan agreed to enact âdeterrence measuresâ and to swiftly deploy troops to bolster the oilârich kingdom and counter Houthi attacks in Yemen.
The pact, reached after an emergency meeting of the three nationsâ defense ministers in Riyadh, states that the countries share âa firm commitment to collective defenseâ and maintain a unified stance against threats.
Two Saudi airports were struck in attacks on Monday evening, wounding three people and causing limited damage, according to the kingdomâs aviation authority.
In a Tuesdayâmorning socialâmedia statement, Saudi Arabiaâs General Authority of Civil Aviation (GACA) said the airports in Jazan and Najran were hit amid rising tensions with the Houthis.
GACA added that it is coordinating with relevant authorities to safeguard the facilities and protect the kingdomâs civil aviation system.
Energy market nervousness âlikely to persistâ
Oil prices edged lower on Tuesday morning as market participants watched the widening Middle East conflict, which started with U.S. and Israeli strikes on Iran in late February.
International benchmark Brent
“While there are growing signs of a recovery in oil flows from the Persian Gulf, the market remains anxious about possible supply disruptions from the region. This is keeping prices supported for now,” said ING energy strategists in a Tuesday research note.
“Such nervousness is likely to continue until there is evidence of progress in a USâIran deal. Meanwhile, the risk of further escalation remains very real,” they added.

Russia plague: What we know about the suspected case reportedly linked to a lab workerâs death
According to local media reports, as many as 189 people have also been placed under medical observation in Irkutsk in eastern Russia.
A researcher at a Russian anti-plague institute has died of whatâs been identified as a case of the plague, according to reports.
Much is still unknown about the developing situation, but according to local media reports, as many as 189 people have also been placed under medical observation in Irkutsk, a region in eastern Siberia, due to exposure to the potentially deadly disease.
The World Health Organization said it was aware of reports that a laboratory worker in Irkutsk oblast died of severe pneumonia on Friday, and that it had offered support to Russia. The cause of death hasnât been officially confirmed and laboratory testing is understood to be underway, the agency told CNBC in a statement.
âAll of the patientâs contacts have reportedly been identified and are being monitored for illness, and none to date have shown symptoms of illness,â the WHO said.
What is the plague and how does it spread?
Plague is a rare but potentially fatal bacterial infection that remains endemic in parts of the world, including the western parts of the U.S., but can be treated with antibiotics if identified quickly. Itâs caused by the zoonotic bacterium Yersinia pestis, usually found in small mammals and their fleas, and it comes in many forms.
Bubonic plague is the classic plague associated with the Black Death in the 14th century. Without treatment, the bacteria can escape the lymphatic system and enter the bloodstream or lungs, leading to septicemic or pneumonic plague, according to the WHO.
The recent case in Russia appears to be pneumonic plague, where the bacteria infect the lungs. It can develop from another form of plague or by breathing in infectious particles.
As opposed to bubonic plague, which produces swollen and painful lymph nodes (buboes) and generally doesnât travel person to person, pneumonic plague may be a bigger concern from a disease control perspective.
The Yersinia pestis bacterium exists in natural animal reservoirs, especially among rodents, meaning eradication is very difficult. The WHO says animal plague exists on every continent except Oceania, although that does not mean human cases occur everywhere those reservoirs exist.
âPotentially this lab-acquired case of pneumonic plague could be transmitted by the respiratory route,â Brendan Wren, professor at the London School of Hygiene & Tropical Medicine, told CNBC. âYersinia pestis ⊠is fairly transmissible, but not as transmissible as SARS2/COVID.â
Whatâs happening with the suspected case in Russia?
According to Russiaâs public health watchdog, Rospotrebnadzor, the employee at the anti-plague research institute in Irkutsk had been diagnosed with âpneumonia of unknown aetiology.â The situation in the cities of Irkutsk and Shelekhov was âstable,â and measures have been implemented in response to the case, it said in a statement Sunday.
Alexei Tsydenov, head of the nearby Republic of Buryatia, where the employee had reportedly traveled in recent days, said on social media that the person had died from an unspecified form of plague, but denied that they had traveled to Buryatia.
CNBC has not been able to independently verify the reports. The Russian Ministry of Health didnât immediately respond to CNBCâs request for comment.
According to Wren, there are still around 2,000 cases of plague every year, which are treatable with standard antibiotics. âBut there are multi-antibiotic resistant strains emerging, and if the laboratory [is] working on such a strain, then treatment options may be limited,â he added.
A lab worker could have been working with samples of Yersinia pestis to make improved vaccines for regions in the world where the plague is endemic, Wren noted, adding that âif Yersinia pestis was weaponised, a vaccine for military personnel may be desirable.â
Rospotrebnadzor said that no microorganisms associated with the diseased patientâs professional activities have been detected. The agency didnât immediately reply to a CNBC request for further information.
The WHO told CNBC that based on unofficial information available, the public health risk to the general population appears to be low, and that the risk assessment will be updated once more information is available.
