Keep getting the message on new Tab page..."500 Internal Error". Tried a search of it, found correction suggestions...did a soft & hard reboot=nothing. Tried finding the Firefox Cache, that said to delete, but can't find that file in the Settings tab in Firefox. So can't do any searches in Firefox for 2 days now. Can you help to resolve this? Or, do I have to delete Firfox & go to another browser?
