Hi JanSull1740, Your issue may be because you've been hit with some [https://support.mozilla.org/en-US/kb/Is%20my%20Firefox%20problem%20a%20result%20of%20malware?s=malware&r=0&e=sph&as=s#w_how-do-i-get-rid-of-malware Malware]. I'd say that is the most likely cause. If it isn't malware, you should take a look at the Knowledge Base article [[How to set the home page]]. Your homepage might have been changed by a particular site. Sites like MSN, Yahoo, etc have been know to ask to become your homepage. There are steps in that article to reset your homepage preferences to default. I would try that first to clear out any strangeness. If that works, you can try setting your homepage again to your personal preference. If that doesn't work you should look at the article [http://kb.mozillazine.org/Preferences_not_saved Preferences not saved]. Hopefully this helps!
