Seeing unblocked ads? Start here!

Are you seeing unblocked ads while using AdBlock? Start by walking through these basic troubleshooting steps if you’re concerned that AdBlock isn’t blocking ads properly.




Is AdBlock installed/enabled?


Desktop:
In order to confirm that AdBlock is installed, check for AdBlock in the list of extensions installed in your browser:

  • In Chrome or Opera, type about:extensions in the address bar.
  • In Safari, go to Safari > Preferences > Extensions.
  • In Edge, click More (...) > Extensions.
  • In Firefox, open the Firefox menu, select Add-ons, and then click Extensions in the sidebar.

If AdBlock isn't installed, here's how to install and enable it.


Mobile:

In order to confirm that AdBlock is installed, on your mobile device, check for AdBlock in the list of installed apps or browser extensions:

  • On your iPhone or iPad, look for the AdBlock icon in your apps.

  • On your Android device using Firefox, look for AdBlock in your Firefox Add-ons list.

  • On your Android device using Samsung Internet browser, look for the AdBlock icon in your apps.

If AdBlock isn't installed, here's how to install and enable it.

Could it be malware or adware?

If you’re experiencing any of the following, it’s possible you’ve been infected with adware or other malware:

  • The same ad on every site you visit

  • Explicit or inappropriate ads on multiple websites

  • Multiple pop-ups and ads on multiple sites, even with an ad blocker enabled

  • Your browser’s homepage changing without your consent

  • A browser toolbar or extension that you don’t remember downloading


Follow these steps to check for and remove malware from your computer or mobile device. Even if you’re not sure it’s malware, it never hurts to scan for infections in order to keep yourself safe.
Is the site whitelisted or is AdBlock paused?

Desktop: 


  • For Safari: Unlike in other browsers, it’s not possible to tell if AdBlock is paused by looking at the AdBlock icon in the menu, since it never changes color in Safari. To pause or unpause Adblock for Safari, see these instructions for disabling and reenabling AdBlock in Safari.

  • For all other browsers: In order to check if AdBlock is paused, look at the AdBlock icon in your browser toolbar. If the stop sign is green (in Chrome, Firefox, and Microsoft Edge) and the hand has changed to a thumbs-up, it means AdBlock is paused or you have whitelisted the page or site. (The AdBlock button never changes color in Safari.)

                         


Unpausing AdBlock is as simple as opening the AdBlock menu (by clicking on the AdBlock icon in your browser toolbar) and selecting “Resume blocking ads.”

Mobile:


AdBlock on iPhone, iPad and Samsung Internet don't have a pause feature. The only way to disable AdBlock on these devices is to temporarily disable content blocking. Here’s how to check whether content blocking is enabled or AdBlock is paused on mobile:


  • In iOS, open Settings > Safari > Content Blockers to confirm your content blocking settings. If you don’t see a Content Blockers option in your Safari settings menu, it means you most likely don’t have AdBlock installed. If AdBlock isn't installed, here's how to install and enable it.

  • In Samsung Internet Browser, Tap the browser menu (the three vertical dots in the upper-right corner). You should see an option for View without content blocker. If you don't see the option View without content blocker, it means you most likely don't have AdBlock installed. If AdBlock isn't installed, here's how to install and enable it.

  • Firefox allows you to pause and unpause AdBlock from the browser. Tap the browser menu (the three vertical dots in the upper-right corner). And tap AdBlock. You should see Pause AdBlock if AdBlock is enabled. If AdBlock is disabled, you’ll see Unpause AdBlock. Tap Unpause AdBlock to re-enable AdBlock. If you don't see the AdBlock menu option, it means you most likely don't have AdBlock installed. If AdBlock isn't installed, here's how to install and enable it.

Are you browsing in private mode?

  • In Safari and Firefox, private mode doesn't disable extensions, so there's nothing special you need to do to use AdBlock in private mode.

  • In Chrome and Microsoft Edge, extensions don't run in private or incognito mode by default. You need to enable them. Here’s how:


Chrome:

  1. Type chrome://extensions in the address bar.

  2. Under AdBlock in the extensions list, click Details.

  1. Scroll down and click the toggle switch next to Allow in incognito to on.


Microsoft Edge:

  1. Click the More (...) button and select Extensions.

  2. Point to the AdBlock button and select Settings (the gear icon in the upper right-hand corner)

  1. Scroll down and check Allow for InPrivate Browsing (if it’s already checked, that means it’s enabled. You’re all set!)

Do you have Acceptable Ads enabled?

If you’re only seeing ads occasionally, and they’re not annoying or intrusive, you may be seeing Acceptable Ads. AdBlock doesn’t block these ads by default (here’s why we choose not to block non-intrusive ads). 


In order to see your Acceptable Ads settings, open the AdBlock menu (by clicking the AdBlock icon in your upper right-hand corner of your browser) and select the gear icon to open the General Options page.


Are your filter lists up-to-date?

If you’re seeing ads on websites that previously didn’t have ads, there may be an issue with your filter lists. A good first step in troubleshooting filter list issues is to perform a manual update. For guidance on updating your filter lists, please see our knowledge base article: How do I manually update my filter lists?
Are you using more than one ad blocker?

If you have more than one ad blocker enabled, disable all but one of them. You might think more ad blockers = more blocked ads, but many ad blockers can interfere with each other’s functionality, making it more difficult to block ads. If you’re not sure whether you have more than one ad blocker installed, follow our instructions for checking to see if AdBlock is installed. You should find any other ad blockers in the same places: How can I check whether AdBlock is installed?
Are you using a different ad blocker?

It may seem like a silly question, but there are a lot of ad blockers with very similar names out there. If you’re using AdBlock Plus or another similarly named ad blocker, you’ll need to follow their instructions for troubleshooting unblocked ads. If you’re unsure, follow our instructions for checking whether AdBlock is installed to confirm which ad blocker you’re currently using.
Nothing’s working. Now what?
