Firefox : Force full-screen mode from webpage

Question

I am developing a web-based database that needs to be opened through firefox web browser(because of some css3 elements). I want the page to open automatically in full screen mod

Answer 1

Can't be done if you just have control of the webpage. Controls in the webpage cannot cause changes in the browser instance itself.

It would be a security issue if that were allowed. You could look into writing a Firefox extension to do that, as they have more access to the browser instance itself.

You shouldn't look at trying to hide the firefox menu controls. That seems like a flaw in your problem-solving approach.
