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 “ Google “ Anything. 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.

After the problem is fixed, Bookmark and use this; Mozilla Search Reset. https://addons.mozilla.org/en-US/firefox/addon/searchreset/

This add-on is very simple: on installation, it backs up and then resets your search preferences and home page to their default values, and then uninstalls itself. This affects the search bar, URL bar searches, and the home page.

I didn't have any Extensions in the Add-on Manager. The only Google program on my PC is Google Chrome. I can't delete it because I need a second web browser so I can have multiple sessions open in the accounting software I use. IE is not certified with the accounting software. After installing the Mozilla add on, my home page stayed as the one I selected until I closed out of Firefox. When I opened a new session, Google.com was once again my home page.

Does the home page setting gets changed in Options/Preferences or is this about the page that opens on startup?

You can check the target line in the Firefox desktop shortcut (right-click: Properties) to make sure nothing is appended after the path to the Firefox program.

You can check for problems with preferences.

Delete possible user.js and numbered prefs-##.js files and rename/remove the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in current Firefox releases.
