Browser plugin help?

Question

JavaScript

Is there anyone who wrote a plug-in for the browser?

The task is to build a plugin with which we can send information to the site, i.e. you need to create a synchronization of the site and the plugin.

How to organize this synchronization of the site and the plugin?

Maybe there are useful articles about what needs to be written where to make it work.
