Send message to other addon
This is an advanced command that enables you to send messages to other add-ons, which then can be used to run other add-ons functionality, if the add-on supports it.
There are several ways to find out the ID of an Add-on.
Opening about:debugging by typing it into the URL bar will display a list of your installed add-ons with their corresponding ID. Ensure that you take the extensions ID (highlighted with green in the screenshot) and not the internal UUID.
