Many features, well listed settings, but only needed one solution Rated 4 out of 5 stars

My only wish was to group tabs from the same site together. I have 311 tabs, Session Manager reports

It changes how tabs are displayed. Instead of just using the mousewheel to skim thru tabs right to left, this groups them all together in a top to bottom form.

Yes, I set it to be beneath the Bookmark Toolbar, but it still does that vertical list. I couldn't figure a way for the classic tab layout + skimming, so it's gone now. Sorry, really hope this can be achieved though
