After upgrading to firefox-3.0.6 I get "Segmentation fault" on my AMD64 amd-cpu. Firefox 3.0.6 compiled and runs OK on Intel based ADM64 I thought maybe it could be somehow related to this bug: http://bugs.gentoo.org/show_bug.cgi?id=252302 so I recompile it against new glibc-2.9_p20081201-r2 but it didn't help, when I try to start firefox in terminal I still get: Segmentation fault Firefox compiled without any errors.

Please help us a bit more and provide some kind of backtrace of the segfault. If you don't know how to achieve this, have a look at http://www.gentoo.org/proj/en/qa/backtraces.xml which should contain all necessary information.
I've re-compile previous ver. firefox-2.0.0.19 and it works OK. Now, I'll try to recompile again 3.0.6 and provide a backtrace. Though, I suspect the problem might be with Mozilla code as Googling is showing some other distros having problem with 3.0.6 "segfault" as well.
I have a problem running backtrace, get not in executable format I have set in make.conf CFLAGS="-march=athlon64 -pipe -O2 -ggdb" FEATURES="parallel-fetch ccache strict nostrip" gdb /usr/bin/firefox GNU gdb 6.8 ... This GDB was configured as "x86_64-pc-linux-gnu"... "/usr/bin/firefox": not in executable format: File format not recognized ls -al -rwxr-xr-x 1 root root 109 Mar 5 14:05 /usr/bin/firefox
emerging Firefox 3.0.7 solved the problem.
