ClicktoFlash/ClicktoPlugin (Mac) is great, you only execute flash if you want to. This little app saves me hours of battery life on my Macbook Air. I don't know what's available on Windows/Linux however if you're on a Mac I can't recommend it enough.

NoSciprt allows you to do that, so does Flashblock. I'm sure there are similar plugins and extensions for browsers other than Firefox (well, maybe not NoScript, it seems pretty unique).

The FlashBlock plugin for Firefox provides "click to Flash" functionality.

Depending on your browser, you might be able to do this directly in browser setting. In newer Opera versions, the setting to enable click to flash is at opera:config#UserPrefs|EnableOnDemandPlugin
