Since entering a site with a video ad playing, I get audio from the ad playing every time I open Firefox. This is version 9.0.1 run on a MacBook Pro with Lion, 10.7.2.

Check the home page setting.


It is also 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).
