Site Switcher од Markus Popp

This addon allows to switch quickly across different version of a web site, like e.g. live/production site, stage site and local site.

The sites can be defined in the setting in JSON format, like this:

[["https://example.org","https://stage.example.org","http://example.org.local"],
["https://example.com","https://stage.example.com","http://example.com.local"]]

If one of the defined sites is accessed, the other sites can be accessed via a popup icon. The non-domain part of the URL will be retained.
