Did you mean fedora-updates-testing.repo?  That's where Firefox 10 is
at present.  Generally you shouldn't have that enabled unless you like
to test new updates and have them break on occasion.

fedora-updates.repo should be enabled by default and remain enabled,
it's the stable updates repository.

You need to list the packages you want downgraded with the "yum
downgrade" command.  So you want to run:
yum downgrade firefox xulrunner

Looking at the update in the updates system [1], several other
packages were upgraded with it, so yum might complain stating those
need to be downgraded too.  Simply add the necessary packages to the
downgrade command to get it to work.

Please also file a bug [2] describing the problem so it gets fixed and
leave negative karma for the update [1] so a broken update doesn't get
pushed to stable.
