Hi Daniel, I'm sorry for the bad advice. (Bad on two accounts, I forgot
that the right name for the pid variable is @{pid}, and that it doesn't
exist under either name in 12.04 LTS.)

Your new rule is fine.

Please file the bug report against the firefox source package; that's the
package that owns the profile.

Thanks
