lodestone display language error

hello, I live in Canada and I speak french. I have a little concern about the displayed language on lodestone and region error.
During the last survey my internet browser(firefox 4.0 it may have been updated after, I don't remember) was set to "French-France" and when I was trying to participate at the survey I was getting a error of region. then I figured out that is was because of my language setting. then when I chose the language "French-Canada" it displayed in "English" but I could participate and I had hard time understand perfectly. as you can see my English isn't perfect :) so if you could see into that I would be really happy

Merci beaucoup !

P.s. I have try in the french section but no answer in weeks.
