As far as I can tell our current www-client/firefox ebuild does not enable marionette support. Could this be enabled, either by default, or controlled via a USE flag? This support enables e.g. selenium-webdriver to drive firefox for unattended testing in a CI pipeline. More information on Marionette in general: https://developer.mozilla.org/en-US/docs/Mozilla/QA/Marionette Information on enabling this in builds: https://developer.mozilla.org/en-US/docs/Mozilla/QA/Marionette/Builds geckodriver may be useful for testing. Upstream is at https://github.com/mozilla/geckodriver and I have an ebuild in my overlay: www-apps/geckodriver-bin::graaff I've tried this patch to see if that enabled it, but it looks like this does not work and I don't know enough about the firefox build system to debug this further. --- a/www-client/firefox/firefox-49.0.ebuild +++ b/www-client/firefox/firefox-49.0.ebuild @@ -202,6 +202,7 @@ src_configure() { echo "mk_add_options MOZ_OBJDIR=${BUILD_OBJ_DIR}" >> "${S}"/.mozconfig echo "mk_add_options XARGS=/usr/bin/xargs" >> "${S}"/.mozconfig + echo "mk_add_options ENABLE_MARIONETTE=1" >> "${S}"/.mozconfig || die # Finalize and report settings mozconfig_final
It looks like this request is not valid because Marionette is available at least in Firefox 50.1.0. Most likely I did not detect this earlier due to issues with my testing setup and due to the fact that the --marionette command line option is not shown in the --help output even when available. In any case I've been able to use Marionette with Firefox 50.1.0.
