Personally I just get the CVS version. They are always of top quality IMHO. To compile it I use the following options
./configure --with-x --with-system-jpeg --with-system-zlib --with-system-mng --with-system-png --disable-mailnews --enable-crypto --disable-accessibility --disable-tests --disable-debug --enable-optimize=-O3 --disable-logging --enable-reorder --enable-strip --enable-elf-dynstr-gc --enable-cpp-rtti --disable-jsd --disable-dtd-debug --enable-extensions="all" --prefix=/usr/local/MozCVS
Granted the CVS directory
does eat through 1.5 or so gigs of HD space IMHO it is worth it
