Cross-browser API

The same API requests are available for all browsers. Use unified requests to create code that works seamlessly no matter which browser your readers use.

Cross-domain requests

Request from a script located on one domain to a page or a script located on another domain. You can run your script within the page the user is browsing right now.

Content scripts

Content scripts are JavaScript files that run in the context of web pages. They can read details of the web pages the browser visits, or make changes to them.

Background scripts

A background script is a long-running script. It’s an HTML page that runs in the extensions process. It exists for the lifetime of your extension, and only one instance of it is active at a time.


Ability to auto-update extensions. Update your extension on your server and it will be updated on the user side.
