In April 2015, a German court found the popular browser extension "Adblock Plus" as admissible and acceptable, after two German publishers claimed it to be illegitimate.

In the abovementioned lawsuit, the publishers claimed the extension to be "anticompetitive", given that it limits their ability to compete in the advertising market by blocking ads. They also claimed that the extension causes damages to them, since their ads reach fewer consumers, and that the extension "infringes the freedom of press". Accordingly, the publishers requested injunctive relief by asking the court to prohibit blocking ads on websites owned by them.

The court, however, was not convinced that the extension violates any rights, and ruled thatthere is nothing inadmissible or anti-competitive in it, or with its operators' activities, and accordingly, it upheld the right of Adblock Plus users to continue blocking ads everywhere.  

At the same time, according to a Financial Times report, wireless networks across Europe are examining a type of software that would help them to block mobile advertising, and at least one major European carrier is planning to install consumer ad blocking by the end of this year. The initial plan is to offer customers an opt-in ad-free service. The ad blocker - developed by Israeli tech firm Shine - will affect most banner ads in both apps and browser, although it will not impact many in-feed ad types such as Facebook’s native ads.
