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.
When adding a web app, see recommendation P02 in CONTRIBUTING.md.
Browser extensions that can add the protocol and hostname or even the entire URL to the window title:
