Closing Tabs from content script

[Hemmer]

I'm writing an extension (currently as a content script), and I'm
having trouble with the following section. The trouble is that
"chrome.tabs is not supported in content scripts". What is the
simplest way to get the same functionality? Do I have to use
background.html?

=============== bigbackbutton.js ===============

// fire function if clicked
document.onmousedown = checkPos;

function checkPos(e){

//check if we are on the left edge of window
if(e.pageX == 0){
// LMB goes back
if(e.button == 0){
history.go(-1);

// RMB goes forward
}else if(e.button == 2){
history.go(1);
// MMB closes tab
}else if(e.button == 1){
chrome.tabs.getSelected( null, function(tab)
{ chrome.tabs.remove(tab.id); return true; });
}
}

return true;
}

====================

Yes. This is listed as one of the limitations of the content scripts:

Send a message to your background page and ask it to perform the action on behalf of the content script.

Perfect this works a charm. There's only one final thing bugging me
(if am I allowed to continue in this thread?). Basically I want to
suppress the right-click context menu in a particular situation. I've
tried many things including:

window.oncontextmenu = function () { return false; }

I've also tried returning false for the click event handler. This has
really got me stumped, and it's the only thing stopping me from
finishing my first extension.

Thanks, Hemmer
