If you have a 64-bit machine and are moderately adventurous, you should consider switching over to the dev or Canary versions of Google Chrome, which now support 64-bit processors. If you have one but aren’t so adventurous, be glad that 64-bit support is coming soon to all versions of Chrome. Either way, the new Chrome should be much faster and more stable.
(What, you aren’t running Chrome? Well, OK, perhaps you have your reasons. But I can’t imagine switching back to Firefox or Internet Explorer.)
