It even has a parental tool in the works that well be interested to test out once available.

The best free adblockers, such as AdLock, Incognito Adblocker, and uBlock, are those that prevent all types of ads while also ensuring your privacy.

Although its certainly possible to find a paid ad blocking software, theres no reason to spend money on one.

This list of the best free ad blockers includes a mixture of highly-effective tools for Chrome, Firefox, and more.

Paid ad blockers are typically the best option if you want something that works the best, but many free ad blockers might just get the job done for you.

No ad blocker is perfect, however, so youll find you may need to try out multiple options to find the right fit.

Ultimately, how an ad-blocker goes about blocking ads does not matter so much as long as it doesnt impede your ability to effectively browse the web and doesnt invade your privacy.

However, since Google launched its built-in ad blocker to Chrome and began punishing sites in Google searches for unfavorable ad practices, most reputable sites have reduced or eliminated this style of advertisement, making them difficult to find for effective testing.

We only mention these where available, but did not include them in rating considerations.

Those included Forbes.com, Fark.com, YouTube, and OrlandoSentinel.com.

In the case of Orlando Sentinel, we found that that website utilizes fairly aggressive advertisements that most ad blockers struggle to block.

In fact, only a few ad blockers on our list effectively blocked all ads on Orlando Sentinel.

We scored each free ad blocker based on those criteria and assigned a score based on effectiveness.

Additionally, with the exception of the Stands Fair Adblocker, all of the adblockers listed below are open source software.

Browser plugins or built-in ad blockers can interact with the websites youre using much more accurately than a standalone program operating on your computer in the background.

You can block all types of ads using this plugin, with the most obvious limitation being that its only available as a Chrome addon.

The Stands Fair AdBlocker is not designed for wholesale ad blocking, although you can use it for that.

The company believes in fair advertising and encourages users to whitelist certain ads from different sites.

That included the more aggressive advertisements found on Orlando Sentinel, as well as other display ads, autoplay video ads, and ads on YouTube.

Opera is one of the fastest and most well-built browsers around and was among the first web browsers to have a built-in ad blocker.

After turning it on in the settings, youll find it blocks almost every ad you come across.

The only exception I found was that it failed to block the interstitial ads common on Forbes (the quote ad that often pops up before reading an article).

Most of the other ad blockers we tested did block that ad from Forbes.

That said, Opera blocks every other ad type that we tested, including those on Orlando Sentinel.

Far from being just a browser plugin, AdLock also offers Windows and Android tools that help block ads across your apps.
