Плохая альтернатива No Script, как я понял, не способен блокировать скрипты частично, либо функционал настолько интуитивно неясен.

Does not allow toggling of individual scripts. Each website is all-or-nothing. I wish I didn't have to choose between not seeing any content at all on many websites (especially single-page applications) and allowing every single script in every single advertisement on the page.

That said, it does work, at least on firefox nightly 57 for ubuntu. Don't believe the reviews that say it just doesn't work.
