[Solved] Wrong site language in Firefox

[Malakomaha]

My site have Ukrainian as Default language.

BUT.
My visiters who have Firefox (I asked - both 2.0 and 3.0 versions) says that my shop is IN ENGLISH :gulp: . All except Categories names and currency name.

Because I was filling products only in Ukrainian, they can't see goods' descriptions, there is no Main title text and Introductory text under Homepage' big logo.

On my PC Firefox 3.0 shows my site normally in Ukrainian. Like IE 6.0 and Opera 9.51.
www.browsershots.org shows my site also without any problems in all browsers.

I don't know what is it and how could it happen. Help me please 8-/

I suspect it related to default language of the site.

Now I have 2 languages activated: English and Ukrainian. Ukrainian is default.
I wish I could turn off English and leave only Ukrainian, but I can't do it, because BO can't be translated at all.

I made an experiment on demosite: I have removed the short description to iPod nano in English and have set this description in Czech, set default language as Czech and (see screenshot) site don't show Czech language, it still be in English (empty deleted by me English short description).

So, please
how can I change default language for FRONT OFFICE?

First - clear allways your browser cache and cookies!

Yes, yeeeeeees!!!
1) I asked my visiters to clear their Firefox cache and cookies (they used to visit my site before I set my language as default)
2) I set permissions to all folders where the langs could be anew
AND NOW ALL SHOWS 100% CORRECT!!

Thank you guys!
