Some people use nightlies for example -
Here there are no 64 bit versions that I am aware of?

I do this when the stock version is somewhat behind even the stable
release from mozilla.  eg in f12 the current thunderbird is 3.1.4 but
the current f12 version is 3.0.7, and similar for firefox. Yet this is
still a supported release - yes f13 is up to current stable releases
from mozilla for both of these. However in the mozilla filestore for
latest stable for thunderbird at:


there is no 64 bit version, so if running 64 bit f12 then it would be
necessary to install the 32 bit thunderbird and make sure that
necessary 32 bit libraries were also installed to make it run?

However in the future, say when f15 is still supported but f16 is
current, it may well be that it is more work to run applications such
as this that are more up to date than the Fedora packages either by
messing with multilib library install or building the application for
64 bit from source.

There must be quite a few other examples where people will want to run
specific codes that are not built for 64 bit?   To take the hassle out
of dealing with issues like this I install 32 bit and life is a bit

However no doubt the best decision will emerge from the discussion?
