How we selected and tested Firefox ad blockers
We gathered the list of best ad blockers for Firefox by putting providers to extensive testing and analysis. Here are the most important criteria we looked at:
- Independent testing. We run several tests to ensure that providers deliver on their promises. Such tests as Adblock Tester and Can you Block It help us determine the types of ads you can expect a provider to handle.
- Trustworthiness. We tested and selected only those ad blockers that have spotless reputations, meaning they won’t steal your private data or infect your device with malware. Our picks don’t have any recent data breaches or leaks.
- Adblock capabilities. Our selection process relied not solely on one type of ad blocking. We made sure a Firefox ad blocker also blocked pop-ups, cookie consent notifications, and trackers that may interrupt your time online. We thoroughly looked at what kind of ads the provider can block.
- Additional features. A good ad blocker does not merely block ads. It should also provide additional features, such as URL trimming to remove tracking parameters. Various customization modes are a good measure of the tool's usability.
- Platform compatibility. We tested to see how providers perform on various devices and browsers. Good platform compatibility is important to ensure that an ad blocker is compatible with the Firefox browser on various desktop and mobile devices. This will allow you to have protection on all systems you use.
- Customer support. We made sure each Firefox ad blocker provided reliable and effective customer support, whether that’d be a 24/7 live chat, a community forum, or email ticket support. We picked the providers with fast and informative customer help provided.
- Price. Many providers offer mediocre service for a significant price. Thus, we evaluated how well the price matches the value each provider offers.
Is Firefox built-in ad blocker good enough?
Mozilla Firefox offers a decent built-in content blocker. The browser-native feature can block two types of content – trackers and cookies. Its most notable feature is Enhanced Tracking Protection – it effectively blocks various trackers and malware.
While tracking protection is designed to improve privacy, it can get in the way of user experience. From time to time, Firefox users, who enable tracking protection, can encounter broken or strange-looking websites. That is because, as Mozilla explains it, Firefox must also block the content to block the trackers. Websites often conceal trackers in login fields, forms, comments, videos, and so on. However, Mozilla is constantly working on improving its tracker protection.
Firefox also lets you get rid of the cookies. It’s done by using Total Cookie Protection, which confines cookies to the site that created them, effectively preventing cookie sharing with tracking companies.
So, if you're wondering whether you still need an additional ad blocker for Firefox, the answer is clear – yes, you do. An ad blocker will remove all types of adware. And if you pick an excellent provider, such as Surfshark CleanWeb, you can also get malware protection and other features in the bundle.
How to turn off the ad blocker on Mozilla Firefox?
The content blocker may make the site look broken when it prevents ads and other content featuring trackers from loading. The best way to fix that is to turn off the content blocker on the broken website. This method also works as a whitelisting feature. The process is quite easy:
- Click on the shield icon to the left of the address bar
- Then, toggle the switch at the top of the panel
- That's it, the website is now whitelisted!
Are free ad blockers for Firefox safe?
The short answer is no. Free ad blockers for Firefox aren't safe. While we're all tempted by free services, the truth is that nothing is really free. On the surface, you may not see the difference between some free and paid providers, but free ad blockers come with risks that you should know about.
First, free ad blockers don't necessarily block all ads all of the time. We tested a handful of free providers and noticed a mediocre performance. Missed pop-ups, the inability to block cookie consent notifications, and Google analytics tools are just the tip of the iceberg.
Free ad blockers often fail, but not only at blocking ads. The security they offer needs to be fixed too. Remember the Nano Ad blocker breach back in 2020? The new developers purposely tampered with user Instagram accounts after injecting malicious code into the ad blocker, which had more than 200,000 downloads.
Remember that developing an ad blocker is not simple or cheap. The process requires resources. Thus they are forced to monetize their products somehow. Reputable providers will collect a competitive fee and ensure a top-quality product. Free providers, on the other hand, may track your online activity and sell this data to third parties.
So is a free ad blocker worth the risk? Our answer is – definitely not. Since many trustworthy ad blockers on the market do not break the bank and offer well-rounded protection for your device, taking a risk with a free ad blocker is simply not worth it.
Conclusion
There are many providers that offer a wide range of ad blockers for Firefox, from free extensions to paid apps. But with so many options, choosing the right one can be overwhelming. Some might help to get rid of intrusive ads, malicious trackers, and endless pop-ups, while others prioritize privacy and performance.
While free ad blockers are tempting, they often come with limitations. Paid options usually offer better blocking capabilities, privacy features, and customer support. Ultimately, the best choice depends on your budget and priorities. A powerful Firefox ad blocker will be able to block all sorts of ads, pop-ups, banners, cookie notices, and even phishing attempts.
While all options have merit, Surfshark CleanWeb emerges as the champion for most Firefox users. Its free, comprehensive ad blocking, coupled with its user-friendly interface, makes it the perfect shield against the ever-growing onslaught of online distractions.
