I have just tested Hardy in French and Firefox starts up nicely in French.
What I did.
Install Ubuntu 8.04.3 Desktop with Romanian as default. Install the French Language Support Log in using French Start Firefox.
Firefox is translated and no errors were reported.
I think this was a temporary problem or it is already fixed.
Can you please test it again.
