I'm using the latest version of Firefox on macOS Tahoe. Over the past 2–3 days, Firefox has started behaving unexpectedly.
Issues:
Firefox automatically creates additional Dock icons while I'm only using a single Firefox window. Even if I remove the extra icon, it reappears after some time.
When I open a different Firefox profile, it launches under a new Dock icon instead of using the existing Firefox icon. As a result, I end up with three separate Firefox Dock icons simultaneously.
Firefox also fails to play pronunciation audio on some dictionary websites (e.g., JapanDict). Clicking the speaker icon produces only a brief click with no spoken audio. The same pronunciation works correctly in Safari, suggesting a Firefox-specific issue.
Expected behavior:
Firefox should use a single Dock icon (unless intentionally running separate app instances).
Different profiles should not create unexpected duplicate Dock icons.
Pronunciation audio should play normally, as it does in Safari.
Environment:
macOS Tahoe (latest version)
Firefox (latest version)
