Hi Martin, in Firefox, the Menu button is the button with a stack of 3 lines at the right end of the main toolbar. Does that have the command/information you're looking for?

Is this about the email address you use to sign on to this forum and possibly for Sync?

There aren't three parallel lines near a toolbar. There's no tool bar either. Please advise or just update my email address for me.

What do you mean with There's no tool bar either ?

Can you attach a screenshot?

Maybe you aren't using the Firefox browser and you need some different instructions?
