Flashblock is now integrated into Camino starting from 1.1b. Flashblock whitelisting will be available eventually.

An installer package and Preference Pane for Camino called CamiFlash from nadamac is a available.

Note: Due to changes in Flashblock since this article was written, you should use this version of the code for your chrome.rdf file instead: http://www.nadamac.de/camitools/camiflash_fix.html.
