There is https://www.gnu.org/software/librejs/

    GNU LibreJS aims to address the JavaScript problem described in
    Richard Stallman's article The JavaScript Trap. LibreJS is a free
    add-on for GNU IceCat and other Mozilla-based browsers. It blocks
    nonfree nontrivial JavaScript while allowing JavaScript that is free
    and/or trivial.
    Downloading LibreJS

    In GNU IceCat or any Mozilla browser, you can install LibreJS by
    clicking on this link and following the subsequent instructions:
    gnu_librejs-6.0.13-fx.xpi (601K). 

The git log indicates activity:
http://git.savannah.gnu.org/cgit/librejs.git/log/
so that it might work with recent browsers.
