A new public alpha of Firefox 2 has gone live. The browser, code-named “Bon Echo” (all Firefox versions are named after public parks) is nowhere near ready for prime-time, but it is smokin’ hot fast on my Powerbook, easily twice as fast at managing tabs and tab-switches as the current Firefox. Regrettably, almost none of my Firefox “extensions” (plugins) worked with Bon Echo, but I’m willing to live without them temporarily while I play at crash-test dummy.
