There are various windows that want to disable the use of plugins within their
context. An example of this is Composer windows (see
We currently provide per window functionality toggling via nsIWebBrowserSetup.
We then use nsIContentPolicy at callsites to determine whether or not a "load"
should proceed. What should probably happen here is that the plugin code queries
the content policy via ::ShouldLoad() before loading a plugin. If yes, continue
w/ the load, if no, "stop" loading (presumably though not much "loading" has
occurred already though and this happens at init time).

Does this mean I would be able to have a preference to temporarily turn off

Bug 94035 concerns blocking plug-ins by site; this is about turning
off plug-ins by window. It's probably not a dupe, but it could be a
WONTFIX if the powers that be decide to approach blocking plug-ins
by fixing 94035 instead of this.
A feature to disable plug-ins on a per-site basis would be greatly appreciated,
