Automated startup process


I am making a screen presentation based on a Flash movie.
I am using a 42" LED screen and a Rikomagic Android 4,1 mini PC.
To run Flash from the internet i use Firefox.
I want to fully automate the startup proces so i use Tasker to start Firefox and a plug-in in Firefox, to enter full screen mode.
What i can't do, is to open a certain webpage at startup and hide the menu bar in the buttom of the screen.:thinking: Can anyone tell me if this is possible with Tasker or in any other way.

Thanks in advance...
