Firefox tab groups are here

What happens when 4,500 people ask for the same feature? At Firefox, we build it.

I mean, it's very very cool that they decided to add that feature. But pretending that they carefully listen to the user's voices and eagerly implement their suggestions... Come on...

This time they borked my Sidebery config. :)

It doesn't expand on hover anymore. I will try to update the code tomorrow.
