GNU LibreJSXUL --an add-on for Iceweasel UXP and similars-- detects and blocks nonfree nontrivial JavaScript while allowing its execution on pages containing code that is either trivial and/or free.

Notes on working with the code

Running the addon

Download jpm, then do something like this in the LibreJS directory:

jpm run -b $(command -v iceweasel-uxp)

Debugging

Uncomment lines 24 and 25 in lib/main.js to enable printing of console.debug() statements.

Adding new whitelisted libraries

Releasing a new version

• Update version number in:
• configure.ac
• package.json
• doc/version.texi
• data/display_panel/content/display-panel.html

• git commit and git tag 6.0.14

• Export a tarball:

  git archive --format=tar.gz --prefix=librejsxul-6.0.14/ 6.0.14 >librejsxul-6.0.14.tar.gz

  mv librejsxul-6.0.14.tar.gz ~/releases/librejsxul/6.0.14/

• Generate Makefile

  autoconf && ./configure
  

• Make xpi file:

  jpm xpi
  
  mv librejsxul.xpi librejsxul-6.0.14.xpi
  

• Upload xpi file to AMO. Use signed xpi from AMO for gnu servers, e.g.: gnu_librejs-6.0.14-fx.xpi

• Upload to gnu servers, update gnu.org/s/librejs links
