Repeating error sound when using Firefox

[sblah]

An error sound keeps repeating when I use Firefox. I'm not sure what triggers it as it tends to be intermittent. There's no visual cue or error message and the browser keeps working, but this three-note sound repeats until all apps are closed or the phone restarted. 

Anyone know what's going on?

Hi, this sounds annoying! This usually happens when a background tab or script is triggering a system sound — even if there's no visible error.

Try this:

1. Clear Firefox cache and site data
2. Disable all extensions and test again
3. Check if any accessibility features (like screen readers) are on
4. Try using Firefox in private mode

If it keeps happening, updating Firefox or switching to Firefox Beta for a bit might help. Let me know your phone model and version too — might be a known issue.
