Simple question... How to right click on an email address on Mac OS X?

ZCS 5.0.16
Firefox 3.0.13
Mac OS X 10.5.7

I've received an email and want to add the email address info to the Address Book in the browser.

On a Mac, how do I right click on an email address to add the email info to the AddressBook?

When you mouse-over an email address in the browser, the popup tooltip shows the email info + "Click to compose. Right-click for more options". I'm trying to right click to get the popup menu to add the email address info. On the MacBook laptop with a trackpad, I've tried:
ctrl+click = nothing.
shift+ctrl+click = nothing.
ctrl+command = nothing.
command+click = composes new email
ctrl+alt/option = nothing.
etc.

I've also tried added 2 finger click here, but no go.

Both ctrl-click and (for newer Mac laptops) two-finger-click should work. BUT Firefox is a little wonky on Mac with Zimbra. Ctrl-click actually has an ambiguous meaning because, in Zimbra, it's also used for multiple selection. So sometimes you have to click more than once.

Try it with Safari, you'll see that Zimbra behaves more nicely.

There's an entry in bugzilla about this: Bug 35543 – control key behavior clashes with Macintosh control-click operation
