Yeah, I really dislike flash in websites.
And 40-50 tabs? I don't even run that many apps during the course of my day I don't think. Guess I'm more of a minimalist, I don't see the problem in starting up and shutting down firefox's all day long. I hate having too many windows open at the same time. It bothers me for some strange reason. And as long as the apps I use remember where I was when I left, it's really no big deal to me.
