You can run the extension via chrome.browserAction.onClick and it will receive the URL. You also don’t need the tabs permission just to create a tab.
I've modified the manifest so that it is asking Safari for wider permissions, so that when the permission is granted by the user, the proper URL is returned.
Regardless, with activeTab you can just inject script into the page itself through which you can open a regular popup.
chrome.scripting.executeScript({
func: () => window.open(' archive.ph' + location.href)
})
Currently the extension will suggest that it needs access to every page the user visits, occasionally opening a popup automatically if I remember correctly.For something that’s a glorified bookmarklet, that’s a lot to ask.
