I must add a data point to the contrary: I'm a longtime Firefox user, and ever since they switched to the new Quantum core [1], issues like hanging or crashing (especially with a lot of tabs open) have practically disappeared. Over the last few years, I've consistently had hundreds of tabs open (with up to 100 active) with no problems whatsoever (three different laptops, all running Windows).
