问题 When a user opens a certain page, I want to open that page in an existing tab, before a new tab is opened.

问题 Given that Angular is tied to the views and bootstrapped in the main extension view, I assume the simple answer is "No, not possible", but wanted to confirm as I can't find a definitive answer anywhere. My use case is that the extension will be polling for updated content from an API, and updating the extension's badge when found; I'd love to be able to re-use my API service from the extension's Angular codebase. If not possible, any suggested workarounds for sharing code between the Angular
