I'm also a fan.

On my own computer, I prefer Firefox and the full version, but work doesn't allow "all site access" extensions in Chrome, and I'm really thankful for uBO Lite there.

I could definitely see myself switch on Firefox too, once most extensions move to the v3 security model. A hybrid would probably be ideal: v2-like blocking behavior on an opt-in basis per site for where it's needed, with a better default security posture where it isn't.

(Actually I wish Firefox would backport the v3-like "allow site access only after first extension button click" model that Chrome has backported even for v2 extensions, but that's pretty far down on my wishlist.)
