commit f4e0e76c2583469d74dc1ba35caf6041175b62a5 Author: Mike Perry mikeperry-git@torproject.org Date: Tue Dec 4 16:03:13 2012 -0800

Bug 3547: Block all plugins.

We cannot use the @mozilla.org/extensions/blocklist;1 service, because we actually want to stop plugins from ever entering the browser's process space and/or executing code (for example, AV plugins that collect statistics/analyse urls, magical toolbars that phone home or "help" the user, skype buttons that ruin our day, and censorship filters). Hence we rolled our own.

See https://trac.torproject.org/projects/tor/ticket/3547#comment:6 for musings on a better way. Until then, it is delta-darwinism for us. --- dom/plugins/base/PluginFinder.cpp | 3 +++ 1 file changed, 3 insertions(+)
