good

I would like completely separate profiles similar to Chrome, but this is an excellent half-measure and has worked really well for me.

Amazing addon. Does everything I need. Main reason I got it was because my old youtibe account got banned but I didn't want to have to start a brand new google account. So I made a new one just for youtube. Now youtube opens in it's own container and everything works perfectly.

I have had none of the issues people are experencing here. No popups every time I open a new tab or website. Not sure what those people did wrong.

Quite handy for handling several accounts at the same time. My all time fav addon

"THE" extension. If I had to use only one, this would be it.
