There were warnings when trying to install this extension: Can anybody help me?
 * Cannot load extension with file or directory name Thumbs.db. The filename is illegal.

Make sure you are clicking the right folder, I've done this too. After you un-zip the download, there is the folder (Touken Ranbu Helper 0.2.4 (Updated Monoyoshi)) and then when you click on it there is (Touken Ranbu Helper 0.2.4 (Updated Monoyoshi)) inside, that is the one you want to open in Chrome. So make sure you aren't trying to open the first one, because you will get that error. Let me know if you still can't open it, I can try to help some more.
