I use Mozilla Firefox, and since I am relatively new to Chess.com, I started with V3. It looks okay to me, but it is relatively slow sometimes.
Welcome Chess.com version 3 (V.3)

Maybe, You are right. But, I am very much accustomed to Mozilla Firefox. Maybe, I will use Google Chrome for chess and Mozilla for other tasks.

I am very much accustomed to Mozilla Firefox as well Sir but you control the things not the other way. one bad thing you COULD face it with google, is when it crashes by waves .
Thank you for supporting me Mr. Zoltan.
since years and I am looking for a very important topic which is : the usage of the mathematics in chess calculations would you please to help me in that, I need PDF articles explain the how. again thank you so much Mr. Zoltan...

There's still a Yahoo Chess?
yes for poor people like us... not for you...
I agree with @mrosendhal 100% I use chesstempo
for lichess it is not working for me, ICC is not cool but there are many too strong for me (players) that is why sometimes I use ICC (despite the non-free account)...
chess.com became a social platform for chess community (the ppl who play chess only around the world) in another way I think this site is not cool like before...
again, I am using this site since 2000 the year, since it was www.chesspark.com and it was more for playing chess via net than being a social plat, it was not free yes I know, it was only 2 weeks free then I was in need to change the email to have another 2 weeks free (I am poor)...
any way I am glade you visit my post and I am glade for sharing your feelings...
Love, Peace and Respect for everyone...
be ok be save.
Storm - Egypt 05:17 AM 3 Aug. 2019.

I played Y! (Yahoo) chess 20+ years ago. It had a beautiful interface and I used it mainly to make a private rooms to play friends standard games The public rooms were a total disaster, a cesspool, as were Y! Chess forums. I also belonged to several Y! Chess clubs and they were active and quite nice. I met a lot of nice people there.
This site was never www.chesspark.com . I don't know where that information came from.
I just looked for Yahoo Chess and couldn't find any sign of its existence.
I don't know how things are in Egypt but it sounds like there might be some regional issues.

no Bat, www.chesspark.com is www.chess.com now
I am not inserting any links to hyper the 1st link so you just click on it to found your self at the main 1st page of chess.com
go for this link:- https://www.chess.com/news/view/chesscom-welcomes-chesspark-members-2379
believe me chesspark is now chess.com
and I see you were Y! chess player since a very long time like 1999 the year
well, that is great :? (20+ years ago ???)
you must be over 40 year old...
anyway Erik can tell you about chesspark.com

anyway we are here using this site
all we hope is chess.com will be great again and forever... somehow I feel proud being a member here in front of my friends in my local chess coffee, group and club...

Chess.com bought and assimilated www.chesspark.com. But chess.com was never www.chesspark.com. That was my point. I never understood the reasoning behind it though.
I've been playing online chess since 1996-7. I'm 45.
you are a diamond member WOW
if I am in your place I will use that perfectly via V3
it is more wonderful with that diamond believe me
