TT, analysis board and Cond. moves not working

The tactics trainer, analysis board, and conditional moves are not working for me.  I'm not sure about the trainer, but I noticed the problems with the analysis board and conditional moves on March 1st, when the 10th Chess.com tournament started.  At first I thought it was due to server load, because so many games started that day.  But the problems are still happening today, so I'm wondering if there is another issue.  I am running FF3 on Windows XP Pro SP3.  I have a bunch of add-ons, but I haven't added anything recently.  The only one I have that may cause an issue is NoScript, but chess.com is allowed.

Below is a detailed explanation of the problems with each feature:

Tactics Trainer: I click on "Start Training" and the new window pops open.  I see the problem fine, but the countdown timer never starts.  If it's the opponents move, he never moves.  If it is my move, I can't move a piece.

Analysis board: At first, I couldn't move pieces at all.  Now I can move pieces normally almost 100% of the time.  Sometimes (~70%) I can click "Current" and be taken back to the current game position to try a different variation.  Sometimes though, after clicking "Current," the board does not revert, but instead shows pieces in two squares at one (e.g. where they started, and where I moved them to in a variation).  Other times, it will revert to the current position, but I can't move any piece.  I can almost never (~10%) click the back arrow button to go back a move.  The same goes for clicking on a move in the move list to go to that position.  If I close the window and reopen, I can start moving from the beginning position, but still have the problems described above.

Conditional Moves: When I click on the button, the window opens, but no move list appears.  I can make moves on the board, but no moves appear in the list.  If I click "Add line" a blank move list appears, but when I make moves, they still don't show up.

Is anyone else experiencing these problems?  Are they related to the start of the tournament (server load?)  Is chess.com doing anything about them?  Part of the reason I upgraded my membership was to use the TT more often and to add additional conditional move lines.  Not being able to use these features is very disappointing.

can you say which browser you are using? do you have javascript disabled or impacted in some way? can you try switching browsers for a minute as a test?

Duh.. I should have tried that.  It works in IE7.  I'm using FF3.  I do have NoScript installed, but chess.com is allowed.  There was an update for NoScript and possibly another add-on or two recently, so that must be the culprit.  I will try to track it down on my end.  The only site that NoScript disallows while I'm here at chess.com is meebo.com, which shouldn't impact these features at all.

It's weird that the analysis board works some of the time, and not others.  That's what made me think it was a load issue. 

thanks. yeah, it's not on our end.... you know you can disable meedbo in your PRIVACY page, right? :)

On the NoScript menu allow chesscomfiles.com and your board will be OK again. I also have NoScript.

meebo is on a few other sites I go to unfortunately.  It's easier to just block it across the whole internet. :)

@ninevah: Thanks.  chesscomfiles.com is on my whitelist already.  It must be related to the recent upgrade.  I will play around with it.

The tactics trainer will work if I forbid chesscomfiles.com and then re-allow it.  But still can't get the conditional moves to work, and the analysis board is still fussy.  Maybe it's time to install Chrome. :/
