bug in firefox

Can't you resize it by pulling from the bottom right corner of the chessboard, hocam?

Are you using a streamer layout by any chance?

I have this problem too, but I am using chrome. I am unable to put the board into the desired space. It only happens when playing, in tactics trainer or analysis I can move the board just fine. Can someone help me, please?

Streamer layout needs to be updated. Go to Stylus, Manage and check for style updates and update to a recent one.

My browser is chrome, I am experiencing the same problems. I haven't had any problems with Opera yet. I can recommend it.

Hehe. You should send love to tors42 who actually fixed it:
