Beta Test Pluck for Firefox
I met the principal developer of the Firefox version of Pluck last Thursday at Gnomedex. We talked about the issues involved in building and debugging a large, complex application using XUL and JavaScript.
He directed me to a private download site, and I gave it a whirl as soon as I got home that night. It looked really good, and I am happy to see that they are now opening up the beta. Follow the directions on the page to apply to be a beta tester.
