The fastest way to stop pop-ups depends on your browser
Most phones come with pop-up blocking built into the browser itself — you just need to turn it on. On Chrome, Safari, Firefox, and Edge, the setting is usually already enabled by default, which means pop-ups should be blocked without you doing anything. If they are still appearing, the setting may have been turned off, or you may be using a browser that does not block them by default.
The second layer is your phone's operating system. Android phones have a system-wide setting that blocks certain types of notifications and pop-ups. iPhones do not have an equivalent system setting, but Safari's built-in blocker is usually enough. If pop-ups keep getting through, the problem is often a website you have visited before, an app you installed, or a browser extension that is not blocking them properly.
Key Takeaways
- Chrome, Safari, Firefox, and Edge all have pop-up blocking turned on by default, so check that setting first if pop-ups are appearing.
- On Android, you can also turn on system-wide notification blocking in Settings under Apps or Notifications, depending on your phone model.
- If a specific website keeps showing pop-ups, clearing your browser cache and cookies for that site often stops them.
- Some pop-ups come from apps you installed rather than websites, so check your installed apps if browser settings do not solve the problem.
How to turn on pop-up blocking in Chrome
Open Chrome and tap the three-line menu icon in the bottom right corner (on Android) or top right corner (on iPhone). Scroll down and tap Settings. Tap Site settings, then tap Pop-ups and redirects. The toggle should be set to Blocked. If it is already blocked and pop-ups are still appearing, the pop-ups may be coming from a website you have visited before, or from an app rather than the browser.
If you want to allow pop-ups on a specific website, you can do that from the same menu. When you visit the site, tap the lock icon next to the web address, then tap Site settings, find Pop-ups and redirects, and change it to Allowed for that site only.
How to turn on pop-up blocking in Safari on iPhone
Open the Settings app on your iPhone and scroll down to find Safari. Tap it, then scroll down until you see Block Pop-ups. Make sure the toggle is turned on (it should be green). This blocks most pop-ups automatically. If pop-ups are still appearing, they may be coming from a website that uses a different method to display them, or from an app rather than Safari.
Safari also has a setting called Fraudulent Website Warning that blocks some malicious pop-ups. This is usually on by default, but you can check it in the same Safari settings menu.
How to turn on pop-up blocking in Firefox and Edge
In Firefox on Android, tap the three-line menu, go to Settings, tap Privacy, and scroll down to Blocking. Make sure Tracking content is turned on — this blocks many pop-ups along with tracking. On iPhone, Firefox does not have a separate pop-up setting because it uses Safari's system-level blocking underneath.
In Edge on Android, tap the three-dot menu, go to Settings, tap Privacy, search, and services, and make sure Block pop-ups is turned on. On iPhone, Edge also relies on Safari's system blocking.
What to do if pop-ups keep appearing even with blocking on
If your browser's pop-up blocker is on and pop-ups are still getting through, the first step is to clear your browser's cache and cookies for the website that is showing them. In Chrome, go to Settings > Privacy > Clear browsing data, select Cookies and site data, choose the time range (select All time to be thorough), and tap Clear data. Then close the browser completely and reopen it.
If that does not work, the pop-ups may be coming from an app on your phone rather than a website. Check your installed apps for anything you do not recognize or do not use. If you see an app that looks suspicious, you can uninstall it. On Android, go to Settings > Apps, find the app, and tap Uninstall. On iPhone, press and hold the app icon on your home screen and tap Remove App.
Android system-level pop-up and notification blocking
Android phones have a system setting that can block notifications and some types of pop-ups across all apps and browsers. Go to Settings > Apps (or Application Manager on some phones), then tap the three-dot menu and select Show system. Look for any app you do not recognize, tap it, and select Uninstall or Disable. Some phones also have a Do Not Disturb mode that silences notifications — you can find this in Settings > Notifications.
If pop-ups are appearing in a specific app rather than in your browser, you may need to change the app's notification settings. Go to Settings > Apps, find the app, tap Notifications, and turn off notifications for that app.
When to consider a different browser
If you have turned on pop-up blocking in your current browser and cleared your cache, but pop-ups are still appearing constantly, switching to a different browser may help. Chrome and Firefox tend to block more types of pop-ups than some other browsers. If you are using a less common browser, try switching to Chrome or Firefox for a week to see if the problem goes away.
Some people also install browser extensions that block ads and pop-ups more aggressively than the browser's built-in blocker. On Android, most browsers do not support extensions the way desktop browsers do, but on iPhone, some extensions are available through Safari. Be cautious with extensions — install only those from well-known developers, and check the reviews before installing.
Frequently Asked Questions
Why does my phone still show pop-ups if pop-up blocking is on?
Some websites use methods that are not technically pop-ups — they may use full-screen ads, overlays, or notifications that the browser's pop-up blocker does not catch. Clearing your cache and cookies for that site usually stops them. If the pop-ups are coming from an app instead of a website, you will need to uninstall the app or change its notification settings.
Can I block pop-ups on just one website?
Yes. In Chrome, visit the website, tap the lock icon next to the address bar, tap Site settings, find Pop-ups and redirects, and set it to Blocked. You can also set it to Allowed for websites you trust. In Safari, you cannot set pop-up blocking per-site, but you can clear that site's data to reset its behavior.
Do I need to install an app to block pop-ups?
No. Your phone's built-in browser settings are usually enough. Apps that claim to block pop-ups are often unnecessary and may themselves show ads or collect data. Stick with your browser's built-in blocker and your phone's system settings first.
What is the difference between a pop-up and a notification?
A pop-up appears inside your browser when you visit a website. A notification appears on your phone's lock screen or notification center and usually comes from an app. Pop-up blockers only stop pop-ups; to stop notifications, you need to change the app's notification settings in your phone's Settings app.
If I clear my cache, will I lose my passwords?
Clearing your cache and cookies does not delete your saved passwords by default. When you clear browsing data, you can choose what to delete — make sure Passwords is unchecked if you want to keep them. You will need to log back into websites, but your passwords will still be saved.
