Except Firefox's codebase is large enough that a bug may be introduced
in something that would have affected the previous build without the
patches and it would go unnoticed as I don't produce Firefox builds
daily. I understand people want to do daily? builds to catch this sort
of thing sooner, which I support. Some times it affects new code,
sometimes it affects old code. It's hard to predict.
Additionally, we get security fixes in chunks. Up to 30 at a time and
they come bundled with other "high importance" fixes such as crash
fixes, hang fixes, etc.

Actually, no. Firefox can take up to 5 hours to build. If the build
fails toward the end, it's ~4 hours PLUS 5 hours which is already a full
work day. Considering that there are packages that need rebuilding
currently against the new Firefox, this does have a very real impact on

Honestly, it has been so much that QE expects it these days. The QE
folks in my office hear of a firefox errata coming and start praying
that the arches behave this time. Because any delays for me means
delays in getting packages to them for testing. I run into some odd
issue on non-x86 arches every to every other release, though I will
admit that firefox has not failed while building ppc for quite some time
I realize that I need to support these arches for RHEL anyway, so there
is some priority to fixing/working around compiler issues, but there is
no reason to delay Fedora fixes while we get things resolved.
