What is Adblock Plus?
Adblock Plus is the most popular browser extension available for Mozilla Firefox, Google Chrome, Opera and Android. Its primary purpose is to remove all intrusive advertisements from your browsing experience: YouTube video ads, Facebook ads, banners, pop-ups, pop-unders, background ads etc.
How does Adblock Plus work?
In order to block ads, Adblock Plus requires the so-called filters to 'tell' it which requests to block. Out of the box, Adblock Plus comes without any filters, but, it will offer you to add a filter subscription on first start. With these filters enabled, it can block specific requests from websites, usually the requests to serve an ad. Blocked ads often leave blank spaces or 'Advertising Tags' on webpages. Adblock Plus is still able to remove these with a functionality called 'element-hiding': based on certain specific characteristics, Adblock Plus is able to hide certain elements from the webpage.

First steps
Choosing the right filterlist
As previously described, Adblock Plus requires filterlists to block ads. By itself, Adblock Plus can only see the webpage you are loading, but has to be 'told' by the filterlist which elements to block. When you install Adblock Plus for the first time, it will automatically suggest a filterlist to you based on the language settings of your browser.
There are a two basic lists out there, EasyList and Fanboy's List. These two lists block the ads from the most popular (often English) websites. However, these lists do not block ads on less popular national websites. In the case that you, for example, come from Germany, you will have to subscribe to the national German filter list. In this case, this will be 'EasyList Germany + EasyList'. An overview of all the lists can be found here.
It is important to note that you should not add too many filterlists to Adblock Plus. This will slow down the adblocker, therefore, your browsing. As a rule of thumb, it is highly recommended to not use overlapping filterlists (e.g. choose either EasyList OR Fanboy's List).
You can also use filterlists to protect yourself against tracking, malware, social media tracking etc. Read more about this here.

Solving problems
Adblock Mozilla Plugin
What if Adblock Plus blocks too much?
It might happen that Adblock Plus prevents some site from functioning correctly. Usually, this is not a bug in Adblock Plus but a problem with the filters (or filter subscription) you are using, these filters tell Adblock Plus to block something that shouldn't be blocked. You verify this by temporarily disabling Adblock Plus, if this 'fixes' the problem you are dealing with a bad filter. Please report bad filters by using 'Report issue on this webpage' feature that will automatically collect important data of the current web page:
When asked about issue type, please choose 'Adblock Plus is blocking too much':
Your report will be automatically sent to the maintainers of the filter list that you use. Please have understanding that filter maintainers don't reply to or act upon each of the many reports they receive. Your report will be more likely to be considered if you provide additional information to make the problem more obvious and reproducible.
What if Adblock Plus doesn't block an advertisement?
If you found an advertisement that Adblock Plus doesn't block, please check first whether you are using the right filter subscription. For example, expecting a French filter subscription to block advertisements on a Bulgarian website is unrealistic — you should add a Bulgarian filter subscription for that job. If the filter subscription is right, then the subscription maintainer is probably simply unaware of the problem and you should tell him by using 'Report issue on this webpage' feature that will automatically collect important data of the current web page:
When asked about issue type, please choose 'Adblock Plus doesn't block an advertisement':
Your report will be automatically sent to the maintainers of the filter list that you use.
