Personally, for my computer, chrome is much faster than IE
Which browser do you use?

Chromium/Chrome is the fastest at rendering javascript. I find Firefox/Iceweasel to be faster (and more secure) overall with moderate use of the NoScript add-on.

chrome is the best :) and easy to clear history and cookies nothing has left rather than firefox, you still viewed the recent history lol.

Here we are almost 11 years later, I can give you an update for the best browser to play chess especially bullet chess. I have tried the new opera with all the super performance boost, chrome, edge and Firefox. And the best one for bullet as you don't lose the first 2 seconds at the start of the match, is Firefox.
does anybody use mac? just got it in the mail and I want to know if it is any good for chess.com!!!
