Some of the Talon files for web apps (e.g. apps/github/github_web.talon) use a browser.host matcher. These talon files should work out of the box for Safari, Chrome, Brave, on Mac, but require additional configuration on other browsers/operating systems.
community is set up so that if a URL is found in the titlebar of an application matching the ‘browser’ tag it will be used to populate the browser.host matcher (see code/browser.py). This probably means that you will need an extension to make the browser.host based scripts work.
Browser extensions that can add the protocol and hostname or even the entire URL to the window title:
Firefox:
Chrome:
