I've been using an n100 as my daily driver for months with librewolf and it's fine. I tend to end up with dozens of tabs at least before I finally decide I'll never sort through them and close the window.
16gb of ram also? I think it's youtube more than anything else. I am having a lot of problems with youtube, my other machine is a netbook which crashes while listening/watching to videos on youtube. Not sure why we put all our content (software engineering, etc) on that platform. It's awful.
