It strikes me as a bit disingenuous to criticize the performance of a browser while openly admitting that you haven't tried it.<p>I've been an avid Safari user for years, but switched back to Firefox at 3.6b5.  The performance improvements they've made are incredible, and with the GrApple theme applied, it looks just like Safari.  Plus, I get back some sorely-missed keyboard shortcuts, Firebug's awesome profiling support, and the "snappiness" that I'm used to in Safari.<p>But until you've actually tried the latest release (genuinely - not 10 minutes working from a disk image), please consider refraining from commenting.  An aspect of the software you used to hate might have been improved.
