Anyone who watches videos online needs flash regardless if you love it or hate it, you still need it. There is no getting around the issue. Yes it's unstable and yes it can cause your browser to freeze up and crash, but without any true alternatives right now, it's the only true choice we all have. The clear downsides of flash player is the fact it can freeze your browser and cause your browser to crash. Another downside is at times it will not not let you upgrade, saying you have a newer version already installed. Still as mentioned before flash is one of those products you need regardless if you love or hate it.
