Flash blocking for Camino is implemented using the Flashblock extension from http://flashblock.mozdev.org/. Flashblock is available under the MPL/GPL/LGPL tri-license. The files necessary for operation in Camino are placed in the content directory and referenced by the jar.mn manifest. A contents.rdf file is included to allow Camino to identify the contents of flashblock.jar. Camino's bundled Flashblock extension is currently synchronized with Flashblock 1.5.13+ from http://downloads.mozdev.org/flashblock/flashblock-1.5-unstable.xpi plus the fix for bug 573815.
