is selenium IDE being able to control other installed firefox addons?

[Possum]

Hi, this is an awesome addon when i add it on fire fox.

as far as I found ,the IDE record all the operations on the page
element ,but seems not recording operation on the other addon or
buttons .

like when i visit an website ,I right-click the mouse and select an
add-on menu called sceengrab! to capture the screen ..can this
procedure been automated using this IDE?

thanks for any advise , if this is not the case in selenium ,do you
guys know any way that can fully control the firefox and all it's
addons automaticaly .because the firefox addons are so abundant , this
can lead to so may interesting applications
