I regularly have +100 tabs open since many years now and am used to scroll through them, now since V57 the scroll speed is extremely slow. I'd like to know how this can be fixed but also, why? Why this change? Was it needed? Anyone requested it? I love Firefox, been a user since the beginning, but things like those are painful. Especially when the great advertising camping for this new Quantum promotes speed! Well, I never had an issue with page loading speed yet it's much slower for me now because I gotta slowly scroll my tabs... It's a paradox but I don't think it has to be. I don't believe to make the pages load faster you had to slow down the tabs scrolling speed? Please help.
