What is ad blocking?

Ad blocking or ad filtering is a software capability for removing or altering online advertising in a web browser or an application. The most popular ad blocking tools are browser extensions. Other methods are also available. Simply stated, ad blocking is technology that consumers use to prevent the download or display of advertising. Online advertising exists in a variety of forms, including web banners, pictures, animations, embedded audio and video, text, or pop-up windows, and can employ audio and video auto play. All browsers offer ad blocking ways: either by targeting technologies that are used to deliver ads (such as embedded content delivered through browser plug-ins or via HTML5), targeting URLs that are the source of ads, or targeting behaviors characteristic to ads (such as the use of HTML5 auto play of both audio and video).

How do ad blockers work ?

Ad blockers, relies on filter rules to know what to block, hide, and (in the case of whitelisted sites) allow to appear on the web pages you visit. Ad blocking compares every HTTP (web page) request to the filter lists you're subscribed to and any custom filters you have added. If the URL (web address) of the request matches one of the filters, the request is blocked and the resource is not downloaded.

Is blocking ads legal ?

Multiple court cases have already upheld your user rights to filter your own “http requests” to decide which content and other information enters your network system and devices. An ad blocker is just another tool in a long list of online security and privacy tools that enable us to do this. Of course, this means that it’s not so popular with advertisers, publishers and website owners who depend on advertising for revenue. However, some ad blockers don’t just block ads. Most current-generation ad blockers have an additional layer of technology that goes around technological defenses of ad-block- detection scripts used by publishers. That is where the problem lies because there are some things that you cannot do. For example Circumvention of access controls is expressly against the law in Europe, the U.S. and in all signatory-nations of the World Intellectual Property Organization’s (WIPO) Copyright Treaty. In short, you’re free to block ads, but interfering with the publisher’s right to serve or restrict access to copyrighted content in a manner they approve of (access control) is illegal.

Do ad blockers slow down browser ?

Ad blockers do slow down computers a little as they require memory and processor time to check their ad list. A browser add-on ad-blocker usually takes the least amount of resources as it won't be running a separate program and won't be running at all when you close your web browser.
