What Happened?

I logged on this morning and, without warning, the entire site is different. I can't locate things, the playing board is significantly smaller, I have to scroll to see things that were visible on a single screen, there is no homepage. Is this a glitch or was there a change? If there was a change, can we go back to the original setup?

Further exploration is even more dismaying. There are screens where a third of the board fills the entire screen, requiring constant scrolling to see the entire board. I am afraid that I am finding that whatever happened has made chess.com unusable.

What is going on?

I was informed elsewhere that there may be a browser issue. Is that true?

Cleared Firefox cache. No result. Same issues.

Do you have any plugins or add one?
