This is a most excellent place for technology news and articles.
"Security", haha yeah right
An extension having access to everything on every page you visit is a potential security issue.
Whether that's an acceptable risk for you in order to have an extension that blocks ads is another question.
Extensions by definition are a security issue. For that matter, so is being connected to the Internet in the case of a browser.
