I'd like to setup my Ubuntu to work without Flash (= not installed), but still be able to view videos on sites like Youtube, wisevid, etc.

I want to try this because recently Flash has crashed a couple times. It also often 'feels' sluggish. Also a couple other flash related questions here got me thinking there might be a better way of doing things.

So how should i do this?



Note: Answers that have flash + work-arounds are also welcome.
