Plugins Container for Firefox plays a sound effect. But all of my plugins are ask to activate or never activate.
When this sound effect is played, "Plugin Container for Firefox" shows up on the Sound Mixer, the sound is played, then the container disappears. I have updated all of my plugins and all of them say "Ask to Activate" or "Never Activate". How is this still happening and, more importantly, how do I make it stop?

Hi Byzantine04, Do you click "Allow for this page" when one of the extensions loads in a webpage? Some webpages will detect if an add on that is needed to load the page is installed.
Else I would try a Malware scan.
Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
You can try these free programs to scan for malware, which work with your existing antivirus software:
- Microsoft Safety Scanner
- MalwareBytes' Anti-Malware
- Anti-Rootkit Utility - TDSSKiller
- AdwCleaner (for more info, see this alternate AdwCleaner download page)
- Hitman Pro
- ESET Online Scanner
Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one. Windows 8 has antivirus built-in already.
Further information can be found in the Troubleshoot Firefox issues caused by malware article.

What does it sound like?
Some extensions may play audio notifications. To rule out one of those, could you test in Firefox's Safe Mode? That's a standard diagnostic tool to deactivate extensions and some advanced features of Firefox. More info: Diagnose Firefox issues using Troubleshoot Mode.
If Firefox is not running: Hold down the Shift key when starting Firefox.
If Firefox is running: You can restart Firefox in Safe Mode using either:
- "3-bar" menu button > "?" button > Restart with Add-ons Disabled
- Help menu > Restart with Add-ons Disabled
and OK the restart.
Both scenarios: A small dialog should appear. Click "Start in Safe Mode" (not Refresh).
Any quieter?
