Here is how you can stop “America Fuck Yeah” background music from 4chan.
UPDATE (Feb 2012): It has now been updated for shitty tragic music.
UPDATE: It has now been updated for “The Rock” as well.
Install Firefox. Optional: If you use Chrome, uninstall it. Use Firefox.
Install Adblock Plus. In Firefox, go to Tools>Add-ons>Get Addons and search for adblock plus. Install and restart Firefox.
When Firefox starts up, it should ask you for filter list, select any filter list you want… or better don’t select any filter list.
Goto Tools>Adblock Plus Preferences and click on Add Filter. Now enter: “http://swf.4chan.org/oldb.swf” (updated for shitty sad music, Feb 2012) without quotes in the box and press Enter. (see the pic below, Note: The picture below has a different code which was supposed to stop “America Fuck Yeah”.. make sure to use “=uGt0nDKu0cg” instead).
Hit OK. Now, reload 4chan. The music should be gone.
Please let me know via comments if you find that the music has changed and/or the above is not working for you.

amazing. 100 bumps for justice. been trying to figure it out and /b/ just tells me delete system32, alt+4 and garbage like that. Well, I had turned the Team America off by blocking some Youtube thing but I couldn’t figure out the new one, The Rock one… so glad this worked and will keep all of them off from now on.
Block the element http://www.youtube.com/v/uGt0nDKu0cg&autoplay=1&loop=1 with adblock. That’ll stop the Rock crap. This method mentioned here failed for me or I didn’t program the adblock filter in chrome properly.
nice job man, work 100%!
It is’nt working for me :c
The new music object is http://swf.4chan.org/oldb.swf
Block that in ABP to stop listening to moot on his man-period.
Good!Thank’s

is the newest fight the powa .swf string.
UPDATE: Seems the plug-in has changed allot since it’s original posting. To stop that annoying music go to the offending page, select “tools/Adblock Plus/Open blockable items” in the list window at the bottom of the page scroll till you find the .swf file. Right click and select “block this item” (the line will turn red) then reload the page.
