Well... yeah, but it is their own implementation, so FFox extensions would still have to be ported.
Maybe Eric and company are planning on supporting Chrome with Abine.
Speaking of which - Eric, my apologies, I've just been totally slammed at work and haven't had time to dive into the changes/updates in Abine, though I have noticed the extension getting updated a few times. I'm hoping to be able to do some serious playing with it this weekend to see if I can actually switch over.
