I don't get this music with any other browser, only Firefox. ITunes is off. I don't see any setting in Preferences that would cause this. . Apple Care tells me that it's a Mozilla Firefox problem.

Check the home page setting:


It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.

Delete the sessionstore.js [2] file and possible sessionstore-##.js [3] files with a number and sessionstore.bak in the Firefox Profile 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).

I can't seem to find the files you list. Could they be named differently?

PS: I'm not a techie, so a plain English reply is appreciated.
