Hi, I'm working on a Firefox extension where I need to detect print event. I've tried the following approaches: * beforeprint – Fires immediately when the print dialog opens (works correctly in Chrome). * afterprint – Fires immediately when the dialog closes (works correctly in Chrome). * window.focus and visibilitychange – Work inconsistently with noticeable delay, depending on how Firefox handles focus/visibility updates after closing the dialog. Questions: 1. Is there a reliable way in Firefox to detect print event? 2. Are there any known workarounds or events that could be used for this purpose? Thanks.
