Every week, at the same time,Firefox changes the search engine in my preferences automatically from Google to Search Marquis, and it also deletes the bookmark for my homepage. How do I stop this from happening? I keep resetting my preferences, but a week later Firefox changes it again.

Run most or all of the listed free to use malware scanners. Each works differently. If one program misses something, another may pick it up.

Another thought:

On Windows, there is a system-level Task Scheduler you can check to see whether a program is set to run at a specific date/time. Does MacOS have anything like that?

Thank you all. Just FYI, I did find malware, Mafntask. Hoping that getting rid of it will have solved Firefox issue.
