Is there a way to turn off sound in firefox from those annoying flash ads ?

Cause I nearly felt off a chair when one of them caught me off guard a minute ago.

Also, a "flash related" comic from our favourite xkcd.

Flashblock will stop the flash animation all together. It puts a play button on all flash content except what you whitelist. The animation will not play until you hit the play button. flashblock for firefox


FlashBlock will stop any flash items from loading on pages, yet they let you turn on ones you want. I recommend that.

  • Yes, but unfortunatelly it blocks those cute little flash games as well.

On Vista and Windows 7 you could just mute Firefox in the mixer. Apart from that I don't know of a way. (And yes, Flash ads that have sound are definitely a peak of evil.)

You may just try blocking everything that looks like an ad. AdBlock Plus and NoScript work pretty well in that regard.


Banner ads are the necessary evil of the internet - so many companies rely on banner ads to eek out a bit of revenue. But there's a time and a place for them, and trying to read a news story or blog entry with 200 really annoying "look at me now" banners and strips just makes it worthless.

Flashblock will do the trick, but AdBlock will silence them forever - as in, if it doesn't load, it doesn't play. Set the regex settings to a site to download from regularly and you won't see them, period.


The extension, Muter, can toggle sounds on/off for the whole browser.
