There are certain websites for which I like to customize how FVWM treats the browser window (e.g., different styles for different sites). As long as the name of the website is part of the window name, it's not a problem.
Occasionally, however, I'll run into a site where there's no stable name. For example, the online music streaming site MOG.com only includes the name of the artist and song in the window name. Many X clients let you specify your own name, but neither Firefox nor Chrome does. Is there a way to uniquely identify such browser windows (whether from within FVWM or not) when the site doesn't provide a fixed reference? For FvwmEvent, I can use the WindowId but as far as I understand, that doesn't work for Style specifications. Thanks! Claude
