As you all might know, Mozilla is migrating its addon system to WebExtension and so many addons break from version 57+, see more here:

https://blog.mozilla.org/addons/2016/11/23/add-ons-in-2017/

In the past I used "Yes Script" and "No Script" to allow Javascript everywhere and block it on specific sites only. However they are not supported in FF 57 (I'm on beta now) and the developer of "Yes Script" does not plan to upgrade it in the future. But I'd like to block JS on specific sites. Any idea how I might achieve that?

Could I do that modifying prefs.js or user.js? I would prefer to do this without any extension if possible. Thanks.

Solved it by developing an extension myself: https://addons.mozilla.org/en-US/firefox/addon/yesscript2/

uBlock Origin in "advanced mode" can block scripts with so-called dynamic filtering rules. It also distinguishes scripts between inline, 1st party and 3rd party. You can set up a default policy of blocking for all sites and selectively override it for specific sites.

Update:
uMatrix is even better and allows more fine-grained control

It isn't possible to disable JavaScript per domain without an add-on.

NoScript version 10 has been released, it supports Firefox 57.

Or you may want to try uMatrix as a replacement, it's even more powerful in that it allows you to block not only scripts but also cookies, ajax, media, etc. And everything per third-party domain.

It is also still possible to reenable support for legacy add-ons. But you'll have to use Developer Edition or Nightly for it to work. Once you are there, set extensions.legacy.enabled to true in about:config. It's also going to be available in the Beta and Release unbranded builds, but not yet.

I installed the "Disable JavaScript" extension and so far it works fine: https://addons.mozilla.org/es/firefox/addon/disable-javascript/
