Thread:Talk:Main Page/Translate.net Main page does not show right translation for zh-tw users by default

No matter which browser I use, for example, Firefox, Chrome and Opera, Main page of translate.wiki shows zh-hans translations and English strings. Acctually, zh-tw language users should use zh-hant translations instead of zh-hans.

I use Chrome for this screenshot.

For example, I have checked about:config values in Firefox, "general.user.agent" is "zh-TW" and "intl.accept_languages" are "zh-tw, en-us, en". So it does not make sense to use zh-hans, there must be something wrong behind this problem.

After I logged in Translate.net, those strings showed the right translations. However, we should not ask everyone who use zh-TW language to register and log in to have the right translations showed.

The problem seems to extend to Wikipedia.

Can any technical guy help zh-TW language users to solve this problem? Please help.
