问题 I have a Greasemonkey script that works just fine in Firefox and Opera. I struggle with getting it to work in Chrome, however. The problem is injecting a function into the page that can be invoked by code from the page. Here's what I'm doing so far: First, I get a helper reference to the unsafeWindow for Firefox.

I successfully loaded the unpacked extension onto chrome, but when I enable it nothing happens, though the page reloads the extension does not work, instead I

问题 I am trying to write a JavaScript function that will open my extension like when the extension icon is clicked. I know how to open my extension in a new tab: var url = "chrome-extension://kelodmiboakdjlbcdfoceeiafckgojel/login.html"; window.open(url); But I want to open a pop-up in the upper right corner of the browser, like when the extension icon is clicked. 回答1: The Chromium dev team has explicitly said they will not enable this functionality.
