If it is a *i686 system*, there is a problem of lacking of optimization. At http://www.linuxfromscratch.org/blfs/view/svn/xsoft/firefox.html you have a newer version (there is another one newer than that, but changes were not for Linux. There, you will find new instructions, in order to obtain optimization, and then a much faster and smaller firefox, which does not stall at 100% of the CPU. Essentially, if you update gcc to 4.9.2, all optimization can be used. Otherwise, some improvement can be obtained with test $(uname -m) = "i686" && sed -i 's/enable-optimize/&=-O2/' mozconfig || true I've told Christopher about that. It has been discussed in the dev list. I've upgraded gcc to that version in the two machines I use mostly. -- []s, Fernando -- http://lists.linuxfromscratch.org/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
