Occasionally when I start Firefox v 16.0.2 for Mac OS X ( this is the highest version I can have on my computer) audio for commercial / spam sites plays.
I tried deleting all cookies, completely removing Firefox and reinstalling it but it doesn't seem to work. Whatever it is has only affected Firefox. Chrome seems unaffected.

Try to delete the sessionstore.js file and possible sessionstore-##.js files with a number and sessionstore.bak in the Firefox Profile Folder.
- Help > Troubleshooting Information > Profile Directory: Open Containing Folder
Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).
Create a new profile as a test to check if your current profile is causing the problems.
See "Creating a profile":
If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.
