Been using it for a couple of months now at work. It's good.

I also appreciate how intuitively it works. I wasn't aware of this feature when it first landed in developer edition, but after I accidentally created a group with drag and drop, the feature just clicked.

I've been using them for a few weeks now. Lifesaver as I try to organize stupid bullshit that life forces on me.

Considering I've been screeching this to myself, I wonder how they heard.

I'm saving all my tabs on a regular basis for 3 firefox pages. How does grouping tabs impact saving them? Does it create sub folders in the main saved tab folder?

Great. Now do Guest mode. It's a must-have for places like libraries and internet cafes - if Firefox equalled Chrome in this regard it'd easily gain a percent on the market share scale.
