Firefox Calculator Application Button

I have been trying to define an application button for the calculator in Firefox.

I have tried creating a button and using the address path displayed in Firefox:

chrome://calculator/content/calculator.xul

Nothing happens.

Could anyone clever than me please help me out?

Thanks a lot.

More of a Firefox question than an Opus question.

According to the list of command line arguments for Firefox you would run this:

"C:\Program Files\Mozilla Firefox\firefox.exe" -chrome chrome://calculator/content/calculator.xul

It does nothing for me but presumably the calculator is an extension which I don't have rather than a standard Firefox thing?

This is the code, I think (I didn't test it, I found it somewhere):

"c:\Program Files\Mozilla Firefox\firefox.exe" -chrome "chrome://calculator/content/calculator.xul"

When I was typing my reply Leo already posted the answer :slight_smile:

Thanks to both of you Leo and Christaan

That works a treat.

Thanks again.
