Mahjong Sanctuary play and stop

Hi all, is anyone else having problems with Mahjong Sanctuary?

It will load and I can play, but when I click on the tiles they just sit there for a second then finally pair up and move to the left holding board. It has been like this for a long time, months, That is why I quit playing it. I thought by now it would be fixed.  This is the only place i can find to report a problem. I'm using firefox with windows 11. Computer and browser were both cleaned. 

Can anyone help me out.? Thank you
