MOZILLA WARNS GERMANY COULD SOON DECLARE AD BLOCKERS ILLEGAL

Summary from the TLDR InfoSec newsletter

Mozilla has raised concerns about a recent ruling by Germany's Federal Supreme Court (BGH) in a case brought by online media company Axel Springer against Eyeo, the makers of the Adblock Plus browser extension. Axel Springer claimed that a website's HTML/CSS is a protected computer program, and therefore, ad blockers that interact with in-memory structures such as DOM, CSSOM, and the rendering tree should be considered unlawful reproduction and modification. The lawsuit has significant implications for other types of browser extensions that alter the DOM, as well as ad blockers.
