You will need one of the many flavors of the Mozilla browser to use LibreJS. It can be installed on the following:
GNU IceCat, Mozilla Firefox, Trisquel Abrowser, Debian Iceweasel.
LibreJS works on these browsers starting from version 29. We recommend that you use the latest version of your Mozilla browser. LibreJS has been tested extensively on multiple GNU/Linux distributions, but it is compatible any operating system as long as you’re using a compatible Mozilla browser.
LibreJS uses the Mozilla
jpm tool, a set of utilities for
creating, testing, running and packaging Mozilla Jetpack Addons.
You do not need
jpm to use the LibreJS xpi file or to install it
using the packaged version, but it is required in order to package the
LibreJS source code into an xpi file. If you would like to run the
tests for LibreJS or make changes to the source files, you
jpm as well. For the “make” command to work
properly, you must have the
jpm command available on your system
from the command line.
You can find information on getting
jpm at these links:
