Flash/HTML5 elements block

[rey]

Thanks for your suggestions.But these already can be set by settingpage, "Under the hood"->"Privacy"->"Content settings...".The setting is very detailed.

now i see it, but can't confirm it's "very detailed" as it works too overall = block all flash on page or allow all flash on page.
it's bad to compare, but extention FlashControl makes it much more deliberate. why bother when there is extention?- 'cause internal things are always better.! 
still thanks for pointing out present function and to devs for providing it -some of chromium-based browsers don't provide such control.
