Thanks - I thought that if the FF3 was didn't offer that by itself, I wouldn't be capable of finding it. Which means this version is really good - I'm getting spoiled.

Also, after 30 hours and regular load it still stands at 100M of used memory, which is great, compared to 2.x. And it's still snappy.
