Yes, -Os seems indeed to be a good flag to compile firefox with. I remember reading a pdf created by some redhat guys about various optimizations on mozilla and they came to the conclusion that -Os what pretty optimal. So the mozilla/firefox/thunderbird rpms in RHEL/fedora are built with -Os, and so are the official mozilla.org builds. Actually I opened a bug report about that to: https://bugs.gentoo.org/show_bug.cgi?id=107584 -- Simon Strandman <simon.strandman@×××××.com> -- gentoo-amd64@g.o mailing list
