i upgraded to www-client/mozilla-firefox-2.0.0.1-r2, and it worked. since i upgraded to x11-base/xorg-x11-7.2 i get strange behavior from X there is no mouse cursor on my left DVI of twinview, it crashes sometimes, when i interact with firefox ( open a new tab, close a tab ...) and in my logs i can see this: X[20016]: segfault at 0000000000000001 rip 00002ac25549275c rsp 00007fff58ca2520 error 4 Reproducible: Always

http://gentoo-wiki.com/HOWTO_Xen_and_Gentoo#TLS_and_CFLAGS "Note: The '-mno-tls-direct-seg-refs' flag does not make sense on any 64bit system. For such systems you can skip the recompilation of the whole world and just recompile glibc " man gcc "-mno-tls-direct-seg-refs Controls whether TLS variables may be accessed with offsets from the TLS segment register (%gs for 32-bit, %fs for 64-bit), or whether the thread base pointer must be added. Whether or not this is legal depends on the operating system, and whether it maps the segment to cover the entire TLS area." This is the only reference I cant find to that CFLAG. Seeing it is a non-supported CFLAG ( at least as far as I can see ) I would only humbly suggest you try compiling Xorg (and maybe firefox ) without it ( thats if you haven't already ) and see where that gets you.
i use x11-drivers/nvidia-drivers-1.0.9746. now run the X and firefox recompiled without that flag. ( i don't know how that got included i my make.conf, i don't remember if i put it there) it looks stable for now.
X[4973]: segfault at 0000000000000001 rip 00002af3ecef975c rsp 00007fffc0e46c90 error 4 happened again, reopening
i noticed flash on the page that i was trying to close when X crashed. so i unmerged net-www/gnash-0.7.2 let's hope that caused it.
I don't know what version of Flash you were using but there was a bug that caused the first beta of flash 9 to crash if you had DefaultDepth 16 in your xorg.conf.
