pageAction doesn't show in a browser popup window

问题

I'm not talking about the pageACtion's popup.html, but a browser window of type "popup".

I have an extension that shows a pageAction on a certain url (as usual). But the pageAction's button doesn't show if the url is in a popup window.

Couldn't find anything about it in chrome extension's documentation. Is it so, doesn't work in a popup typed window, or is it happening to me, because I'm using Ubuntu 13, for example?

回答1:

Thanks to @apsillers contribute, I conclude Chrome's popup window interface doesn't support browser actions nor page actions, by design.

chrome.pageAction.show on a popup window doesn't work, neither throws any error.

I think the location bar in a popup window isn't an omnibox.
