If you’re using Google’s Chrome browser, be sure to update it to the latest version (version 1.0.154.48 as of today). A critical security flaw has been found which is fixed in the latest version.
Google Chrome is a great browser for limited applications, especially Google’s own applications like GMail, Google Documents, etc. Chrome has been optimized for Javascript and runs Javascript noticeably faster than Firefox or IE.
I use Chrome for GMail, Google Calendar, and Google Documents, primarily. I use Firefox for everything else because of the rich set of plugins available. It’s a bit of a pain switching back and forth, but the additional speed in GMail is well worth it, IMO.
