I’ve recently developed a Chrome extension which retrieves content from a page, and sends it to the server. The following approach was used: File downloads: Get the src property of an <img> element, for example. Fetch the file from the Cache – use XMLHttpRequest from the background page.

Register a content script in the manifest file at “run_at”: “document_idle” (which is the default) and put your code in the content script file. Then the script will be run when the page is ready.

No. Only ftp:, file:, http: and https: can be matched by a content script declaration. Invalid URL patterns at any of the matches and exclude_matches fields are rejected (generating an error when trying to load the extension). Invalid patterns at the permissions option in the manifest file are ignored. If you want to run a … Read more
I was looking for the same thing. Thanks to the help of the user wOxxOm I’ve figured out what to change inside the manifest file. Here is an example of how to migrate manifest.json from v2 to v3. First thing is to change the manifest_version key from 2 to 3 //Manifest v2 “manifest_version”: 2 //Manifest … Read more
