Hello, please refer to the [[How to set the home page]] support article for detailed instructions on how to properly set your home page on your web browser. You might also want to get your computer checked up for viruses and malware, as some of them can sometimes affect your web browser and change its default home page in an attempt to infect or phish you. I personally suggest Malwarebytes' Anti-Malware (http://www.malwarebytes.org/) for detecting and removing malicious software. Thank you for your patience and have a nice day! -- Kind Regards, Tristan 'Natrist' C. Mozilla Support https://support.mozilla.org/
