mozilla@gentoo.org Gentoo Mozilla Team Disable official Firefox branding (icons, name) which are not binary-redistributable according to upstream. Build with user-specified compiler optimizations (-Os, -O0, -O1, -O2, -O3) from CFLAGS (unsupported) Use the cairo-gtk2 rendering engine Allow Gecko Media Plugins (binary blobs) to be automatically downloaded and kept up-to-date in user profiles Use gstreamer:0.10 instead of gstreamer:1 for media support Force-enable hardware-accelerated rendering (Mozilla bug 594876) Enable or disable jemalloc Enable or disable jemalloc3 (forced-on when supported prior to 38.0) Add support for profile-guided optimization using gcc-4.5, for faster binaries. This option will double the compile time. Enable the SKIA engine for 2D rendering as an alternative to cairo Enable support for using rust compiler (experimental) Use the system-wide x11-libs/cairo instead of bundled. 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. Use the system-wide dev-db/sqlite installation with secure-delete enabled
