It is first addon that really blocks that annoying service-workers feature (in my opinion - SW's is just another tricky way to track you or deliver something malicious to your browser using cache) . I wonder if there is version for chrome?

Works well. Would rate five stars if allowed site exceptions. Must disable add-on to log into sites that require service workers. Otherwise works well.
