Hi Nancy, where have you found changes? For example: * startup/home page has changed -- please see: [[How to set the home page]] * when searching from Firefox's address bar or the new tab page search bar, Bing is used -- please see: [[Change your default search settings in Firefox]] If those changes work, great. If those were already fine, could you describe in more detail the sequence of events that lands you on Bing? If the changes only work until the next time you exit out of Firefox and start it up again, we can suggest possible reasons for that.
