Epiphany is using the plugin directory of the browser it was built with (be it Mozilla or Firefox), and not also looking into our global plugins folder, which causes it to load no plugins at startup. An easy fix for this would be to add MOZ_PLUGIN_PATH=/usr/lib/nsbrowser/plugins to the environment when launching epiphany. Reproducible: Always Steps to Reproduce:
Addendum: I've tested this with USE="firefox" so far, will rebuild it with regular Mozilla and find out as well. But since both /usr/lib/mozilla-firefox/plugins and /usr/lib/mozilla/plugins are directories with nothing but libnullplugin present, it's likely the same issue will take place. This is using epiphany 1.6.4.
Firefox 1.0.6-r2, Mozilla not presently installed.
Taking ownership as this is a Mozilla issue
Fixed in Firefox 1.0.6-r5, which is now stable on x86.
