One of my users was unable to load CKeditor whilst using the German version of Firefox, downloading the English solved the problem.
Is this something to do with Ckeditor detecing the language version then not laoding due the correct langauge config file being there?
I only include English using this line in /lang/ _languages.js but maybe that is the wrong approach?
var CKEDITOR_LANGS=(function(){var b={en:'English'},c=[];for(var d in b)c.push({code:d,name:b[d]});c.sort(function(e,f){return e.name<f.name?-1:1;});return c;})();
I also delete all other lanaguge files in /lang/ except the english ones.

Yes, that's wrong.

That file isn't used at all in the normal editor and IIRC it's used only for the language sample or something like that.
Ok but would that effect this
Ok but would that effect this issue with the German Firefox or is that down to something else?
