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.

Chosen solution

Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; (<Control> [Mac=<Command>] <Shift> A)

In the Add-ons Manager, on the left, select Extensions. Remove “ Search Marquis “ Anything.

Also remove SafeSearch, SearchAssist Incognito, FileConverter Addon, SearchLock, DiscreteSearch, WebSearch, Findwide Search Engine, securedsearch

Now do the same in the computer’s Programs Folder.

Windows: Start > Control Panel > Uninstall Programs. Mac: Open the Applications folder. Linux: Check your user manual.

You may have ad/mal-ware. Further information can be found in this article; https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-caused-malware?cache=no

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.
