I'd like some clever person to invent or tell me where to find
an applet for IceWeasel which would do the following:

1. Indicate if there is flash content in the page I'm viewing;
2. Indicate if my flash plug-in is enabled; and
3. Provide a toggle for flash on or off.

I'd like this applet to be as clever and inobtrusive as that which
goes with Network Manager.
