So you're on the Flock bandwagon, but really miss your Firefox extensions? Turns out that with a little work, it's possible to get most Firefox extensions to work with Flock, but Geoff Gauchet took it one step further and created Flocker. Flocker is a simple utility that tweaks (almost) any Firefox extension to work with Flock; all you have to do is drag the extension's .xpi file onto Flocker and it will spit out a new Flock-friendly .xpi. Excellent!
