And (s)he uses locking?

Yes, Linux does that by default.

Like this:

server:/export/home    /home    nfs    defaults    0    0

Can you please try "defaults,tcp" instead of "defaults"?

    Kind regards

Done. Same old story. It worked for some time, then it stalled, had
to force quite, and when I try to restart it, it won't start.

These are the last lines from "strace firefox":

stat("/home/teemu/.mozilla/firefox/ppr8844q.default", {st_mode=S_IFDIR|0700, st_size=2048, ...}) = 0 open("/home/teemu/.mozilla/firefox/ppr8844q.default/.parentlock", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 15
fcntl(15, F_GETLK

Note that fcntl is intentionally cut after F_GETLK, it is not
a copy-paste problem.

BTW, I don't know if this is a related or a separate problem,
but I get a _lot_ of these on server log both from Linux and Mac OS X:

Nov 25 22:26:43 server rpc.lockd: no matching entry for core7
Nov 25 22:26:44 server rpc.lockd: duplicate lock from core7.27

I know that question has been asked at least one and a half years
ago but I haven't yet found an answer.
