How to Install a Facebook Ad Blocker on Chrome and Firefox (Step-by-Step)

Facebook ads are already challenging enough for us to “swallow a spoonful of bitterness,” but recently, some ads have even become a secret door leading straight into a malware den. The wave of malvertising is accelerating, while Facebook is virtually turning a blind eye to many ads leading users to scam pages or silently downloading malicious files. If we look closer, Facebook’s advertising mechanism operates like a living entity clinging to users’ web browsing habits, which is why you see many bad Facebook ads (porn, gambling, etc.). And amidst this “sophistication without control,” Facebook sets up an extremely loose filtering net for advertisers. Therefore, in this article, BlackHatWorld will guide you on how to select and install the most effective extensions to block dangerous ads on Facebook when using Chrome and Firefox. This is the simplest way to protect your device, data, and peace of mind whenever you browse the web.

How to Install a Facebook Ad Blocker on Chrome
Imagine Chrome as a bustling marketplace, where countless extensions jostle to offer their services. Our mission is to select the right tools to help advertisers and users protect themselves from the malicious ads lurking out there. Therefore, in this section, we will provide detailed instructions so that anyone can personally set up a shield to block unwanted Ads on Facebook right in the Chrome browser.
Opening the Chrome Web Store and selecting a reputable Extension

Open the Google Chrome browser on your computer. When the window appears, we encourage you to navigate to the search bar at the top and enter the keyword “Google Chrome Web Store.” Simply press enter, and Chrome will return a list of related results. Among them, the official link to the Chrome Web Store usually ranks first. Click on this link to go directly to the homepage of the Chrome extension store.
Finding the extension you want
Once inside the Chrome web store, you will see a search bar located on the left or top side, depending on the interface. Here we enter the keyword “Block Site,” and press Enter to search.
Immediately, a list of related extensions will appear. Among them, advertisers and users should look for the correct extension named “Block Site,” usually developed by blocksite.co or similar. Click on this extension to open the detailed description page, where you will see instructions, reviews, and other user information.
Adding the extension to Chrome
On the Block Site details page, we will find the “Add to Chrome” button right on the screen’s right side. Simply click this button, and a pop-up window will appear asking for confirmation. When the pop-up shows up, please select “add extension”. This helps Chrome start downloading and activating the extension. After a few seconds, Block Site will be successfully added, and the extension’s icon will appear in the right corner of the Chrome toolbar.
Customizing the extension to block Facebook Ads
Once the Block Site icon is settled on the toolbar, click on that icon to open the extension’s dashboard. Right on the main interface, you will see a box to enter the desired website address to block. Here, you and I can enter “facebook.com,” then click OK or Add to include it in the block list. Immediately after completion, all access to Facebook will be automatically blocked.
Can I install a Facebook ad blocker on Firefox?
Using an extension not only helps you browse the web faster but also limits the risk of being attacked by malicious ads. We will specifically illustrate this with AdBlock Plus, one of the most popular and easy-to-use extensions on Firefox.
Accessing and installing AdBlock Plus on Firefox

Open your Firefox browser and go to the addons.mozilla.org page. Here, you will see all the extensions that you can add to the browser.
- In the search box, enter AdBlock Plus and press Enter. The extension will appear in the first position in the list.
- Click on Add to Firefox to add it to the browser, then press Add to confirm.
Firefox will ask if you want to allow this extension to work when opening a private browsing window. We personally usually deselect this, because when using private mode, we want a completely “clean” browsing experience without extension interference. You can choose according to your needs and press OK, got it.
Immediately after the installation is complete, the AdBlock Plus extension will be activated. You can check by opening any website, for example, our page, and notice that the extension has blocked the displayed ads on the page. The first time you open the extension, AdBlock Plus may show a notification inviting you to donate. If you do not wish to, you can close this tab and continue using it normally.
Managing AdBlock Plus on Firefox
Managing AdBlock Plus is very simple. Click on the extension icon on the toolbar, and you will see options to turn it off, for example, only turning it off for the current website or turning it off for some specific pages. If you want to completely remove the extension, you just need to right-click on the icon and select Remove Extension.
Firefox allows you to manage all extensions in a single interface. Open a new tab and type about:addons, then press enter. Here, you will see all installed extensions and can click the three dots (…) to open options for detailed settings or select Remove to completely delete the extension.
Furthermore, from this page, you can also add new extensions directly without having to return to the official Add-ons page. This makes managing, enabling, disabling, or updating extensions more convenient and faster.
Installing an ad blocker on Chrome and Firefox helps you browse Facebook more safely, reduces distraction from ads, and limits risks from malicious websites. With just a few simple steps, you can effectively and conveniently control your web browsing experience.
