As long as you have a content script anyway, this should be fine, otherwise, it is just wasteful (there are memory implications for having a content script).

I have the extension write a hidden div to the page, then have a script on your page check for the hidden div's id. If the div is present, the extension is installed. Otherwise, do inline download.

Have a web_accessible_resources entry for a text file or whatever that has the character "1" and use AJAX and the like to fetch it from chrome-extension://extension-id/text.txt and check the response.
Have a web_accessible_resources entry for a text file or whatever that has the character "1" and use AJAX and the like to fetch it from chrome-extension://extension-id/text.txt and check the response.Note that this will make your extension fingerprintable by any website, which is generally bad for user privacy.The most secure way to check if your extension is installed is to attempt to message it. This will ensure that only trusted websites can use this detection, and it will be invisible to other websites (unless it performs some detectable action).
