As of Azureus 3 (codenamed Vuze) a new interface has been introduced. This includes flash content for previewing videos and for some banners. However, Azureus fails to find flash's installation path and, as a result, complains that it is not installed and should be in order to view the corresponding content. Reproducible: Always
The fix for this is to export the MOZ_PLUGIN_PATH variable before running azureus, so adding the line export MOZ_PLUGIN_PATH="/usr/lib/nsbrowser/plugins" at the file ~/.azureus/gentoo.config should fix it.

Fixed in 3.0.4.2-r1. Also added instructions how to fix between different UIs.
