Development version

If you're brave enough and you need a specific feature or fix not released yet, or you simply want to provide feedback before official release, you may want try this
development build.

IMPORTANT: if you're using Firefox 57 you'll need to open about:config and turn the extensions.legacy.enabled preference to true, otherwise the browser will refuse to install Noscript.
NoScript is currently a Hybrid WebExtension, and therefore won't install on Firefox 57 pre-releases without this trick. Before Firefox 57 is released in the stable channel, a pure WebExtension NoScript will be available an you'll be automatically migrated to it.
