Adblock Master Firefox

Adblock Master

By: Kunama
Simple and easy to use, almost no settings required, easily blocks various types of pop-up ads on websites and video ads.

Features & Capabilities

This is an easy-to-use ad blocker extension that blocks over 80% of ad banners, including floating ads, ad columns, and pop-ups. In addition, it can also block video advertisements from mainstream video websites, giving you a member-like viewing experience. Currently, it supports blocking advertising videos from Youtube, Google Ads Video, Naver Video, Kakao Media, Sohu Video, Tencent Video, Mango TV, iQiyi, Playeur, Telemundo, Rotten Tomatoes and Nivod4 TV.

This extension enables ad blocking by default after installation. If you frequently browse Spanish-language websites, it is recommended that you check the "Spanish" item on the "Settings" page to block ads on Spanish-language websites in a more targeted manner. Likewise, checking "Chinese" will block ads on Chinese websites. However, in order to avoid loading too many rules and affecting the speed of your browser, it is not recommended that you check too many language options.

🥑 It's handy to use

It takes less than a minute to open the extension store, find it ,install it, and then make some simple settings. All advertising banners that comply with the rules will be automatically blocked, and you won't even feel it exists.

🍒 Block privacy collection

A page with advertisements will collect more or less all kinds of your private information. But no matter what, we always don't want them to get our "advertising preferences". While it blocks privacy collection, it also speeds up your web browsing.

🍉 Make the website cleaner

Various dazzled ad-banner or ad-frames on the web page will distract our attention. It uses the fewest rules to effectively block more than 80% of advertisements. For example, large advertisers such as Google, Amazon, Baidu, and Yahoo are all on its blacklist.

🥝 Block and skip video ads

Like the ad-banners on the page, the ads that appear during video playback are quite annoying and cannot be skipped easily. We have used some special technologies to give you a smooth viewing experience. Currently, more than ten mainstream video sites including YouTube are supported, and video ad blocking for more sites will be added in the future.

🍄 It's free forever

Adblock Master is completely free, and we have no plans to offer membership features. The development of this extension is entirely a personal interest. In the future, we may open source the program or rely on some donations to achieve income.

Is Adblock Master Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Adblock Master requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Adblock Master may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
