Get window object from tab

Question

I am developing an extension on Firefox\'s Addon SDK (v1.10).

My extension has a toolbarbutton that updates a small badge to its left based on the contents of the ac

Answer 1

Would this be the active window? You can get a window object for the current active window using

windows.browserWindows.activeWindow

Docs: https://addons.mozilla.org/en-US/developers/docs/sdk/latest/packages/addon-kit/windows.html#browserWindows

The window object has a list of tabs currently open in it:

If you need to find a tab in a window that isn't the current active tab or window, that might be more difficult to determine. Can you provide more detail about what you're actually trying to do?

Answer 2

Looking at the SDK source code (namely packages/api-utils/lib/tabs/tab.js), a tab object actually has a window property. I tested it and this works indeed:

console.log(require("tabs").activeTab.window.title);

Not sure why this property isn't documented, probably a documentation bug.
