It works roughly one time out of ten. Sometimes it takes even more than twenty page reloads in order to see the translated version of the Tenhou html client.

Incredible! Thank you so much for creating this tool. I've been playing tenhou for ages, and only after loading this add-on did I realize all of the different options I have been missing out on.

My only minor complaint is that if a name/title has multiple words, every word should be capitalized. An example: 'Change Lobby' instead of 'Change lobby'.

We usually plays mahjong with friends, this extension fine for that!

Completely transformed my experience! Now I can really enjoy riichi mahjong, playing against people all around the world, any time of the day. Translates the gameplay, settings menu, and registration pages into English instantly.
