I just tried it - it's fine.
What you need to do is go to the top right and hit 'create seek'.
The computer will open a window asking for your specifications (just like the regular games). Someone will likely take your challenge.
Or-there may be seeks already that you can accept.
I also use Firefox (on the MEPIS 6.5 Linux system).
Good luck!!!
Is Live Chess broken currently?
When I log in, I just get a chessboard and am able to play both sides. But no opponents of computer options?
Using firefox
