Given that >=www-client/firefox-57 alias Quantum is incompatible with many extensions, gentoo should, at least for the time being, provide the most recent ESR release of firefox. Reproducible: Always
Simply renaming the ebuild unfortunately does not do the trick. The source downloads and builds all right, but the install fails: cp: cannot stat '/var/tmp/portage/www-client/firefox-52.5.2/files/gentoo-default-prefs.js-1': No such file or directory * ERROR: www-client/firefox-52.5.2::local failed (install phase): * (no error message) * * Call stack: * ebuild.sh, line 124: Called src_install * environment, line 5151: Called die * The specific snippet of code: * cp "${FILESDIR}"/gentoo-default-prefs.js-1 "${BUILD_OBJ_DIR}/dist/bin/browser/defaults/preferences/all-gentoo.js" || die; I guess the maintainers must know what the "gentoo-default-prefs" thing is about, I certainly don't.
