It works great for me; my OS crashes much more often (and that's rarely); I'm a heavy user with dozens of extensions installed and often 50-100 or more tabs open. But yours and my general anecdotal experiences aren't useful. There are hundreds of millions of Firefox users; we [EDIT: i.e., you and I] could have great or horrible experiences and they would indicate nothing. Perhaps if we could point to specific bugs our posts would be substantive, though still probably not of much consequence. We need data.
