MrAlex94/Waterfox Build with user-specified compiler optimizations (-Os, -O0, -O1, -O2, -O3) from CFLAGS (unsupported) Disable EME (DRM plugin) cabability at build time Allow Gecko Media Plugins (binary blobs) to be automatically downloaded and kept up-to-date in user profiles Force-enable hardware-accelerated rendering (Mozilla bug 594876) Add support for profile-guided optimization using gcc-4.5, for faster binaries. This option will double the compile time. Use the system-wide media-libs/harfbuzz and media-gfx/graphite2 instead of bundled. Use the system-wide dev-libs/icu instead of bundled. Use the system-wide media-libs/libjpeg-turbo instead of bundled. Use the system-wide dev-libs/libevent instead of bundled. Use the system-wide media-libs/libvpx instead of bundled.
