For me it is that it opens all "most visited sites" in new tabs.
I usually go between 6-10 sites and use tabs mostly as a "read later". Sometime last year I started getting a lot of open tabs, and closing them one by one (to keep my read later tabs) is pretty darn annoying. I switched away from FF for that.
