Why doesn the Pandora player show up in Firefox?
This can happen when the “Adblock” Firefox is installed. In the Adblock preferences, you’ll need to switch off the “Obj-tabs” option for the Pandora Player to show up. To do this, select “Preferences” in the Adblock sub-menu in Tools, then hit the “Adblock Options” button to get a drop-down. “Obj-tabs” is the first check box.
