No, that's the contrary, they reply too fast, in a sense. If you look at
the log I posted, dnsmasq does receive some kind of reply from the
unreachable nameservers. I don't know whether this is a crafted reply by
the firewall or whether the query actually reached the nameserver but it
replied with
What do you mean by "fast enough", though? Do you mean that all the
listed nameservers are very slow, some of them infinitely so (perhaps
because of a routing problem) and dnsmasq either always (William's case)
or usually (your case) times out before any nameserver replies?

What I meant is that DNS resolution always fails at first, and then
after lots of tries, it starts to work. But now that I look at the logs,
it may just have been a fluke: it eventually works because one of the
reachable nameservers happens to reply fast enough.

Here is what I get when routing to the DNS servers goes through the
wrong interfaces. See bug #979067 for additional details on my setup.

Yes, it happens with dnsmasq by itself. However it appears that dnsmasq
is caching the result, so when it sees a good one it will keep serving
it.
Here is some example output from the syslog:

In bug #979067 there is a similar description of apparent dnsmasq
misbehavior.

Does the standalone dnsmasq behave the same way?
To find out, disable nm-dnsmasq by commenting out the line "dns=dnsmasq"
in /etc/NetworkManager/NetworkManager.com. Restart network-manager.
Then install the dnsmasq package.
If standalone dnsmasq also misbehaves then turn on log-queries mode: add

Well when I did a manual dig @75.75.76.76 it timed out half of the
queries. The few responses it gave did seem good. That may not have been
representative though of the overall.
Unfortunately (or fortunately) the issue has stopped happening.
Thank you for your attention to this issue.

The only way I can see for this to occur is if a DNS server is return wrong (ie
NXDOMAIN or NODATA) answers, no answer shouldn't be a problem.
I suggest adding --log-queries to the dnsmasq configuration to try and

DNS Querying fails if any DNS
Well, dnsmasq is supposed to try the servers in parallel and use the
fastest response; not really rotate using one or the other.
It would be useful if you could provide a packet trace of what is
happening when you open firefox and notice this behavior, I would like
to see if dnsmasq really is only
