Hi, this bug isn't related at all with the Swedish locale package. It's Firefox who decides how to render a page, that isn't related with a translation (of Firefox).
I submited a bug in bugzilla.mozilla.org about this: https://bugzilla.mozilla.org/show_bug.cgi?id=287299 which finally was a duplicate of: https://bugzilla.mozilla.org/show_bug.cgi?id=16206 It seems that the enhancement will be included in Gecko 1.8, which means in Firefox 1.1 (if I understood correctly). Regards, César
