It has improved dramatically since then. I'm not saying it's perfect, but I think you should give it another shot instead of complaining about how bad it used to be.
I'm still using Firefox, just dread the day this feature comes back. It is now disabled in my settings, I just wish they make it optional instead of mandatory, because for my use case it brings serious stability issues.
I remember that phase, it was below-alpha quality. It's now okay, no fear to have, only some occasional hiccups like asynchronous errors (click somewhere at time T, click action triggered regarding the element at time T+x).
You can't use beta software and complain about stability issues.
