popup url per Derek Chuank

Before using this extension, click the toolbar button to edit the configuration, fill the url parameter with your wanted url.

Place the string: "????" to the variable part of the url.

For example, with the url configured to "https://cn.bing.com/dict/search?q=????", after I select a text: "vocabulary" in a page using the mouse pointer, this extension will open "https://cn.bing.com/dict/search?q=vocabulary" in this page automatically.

You can fully customized the appearance using CSS in configuration.

Note:

* Some website may restrict external connection using Content Security Policy (CSP). This will cause the extension displaying a blank page.
