1) I open Firefox.

2) Mozilla overrides my home page. Yes, my home page opens but not on the active tab. Instead another tab opens which basically does nothing but brag about the latest version of Firefox.

3) How do I prevent this? (This appears not to be a simple matter of setting the home page. The desired home page was set a long time and is still set. Mozilla just overrides the desired home page.) What do I do to prevent this? Is it possible to prevent this? Is it possible to figure out when this is to occur so I can check to see if I have a macro scheduled that will be abended and require manual intervention?

Thank you to any and all who can help

Chosen solution

hello Sean2, enter about:config into the firefox address bar (confirm the info message in case it shows up) & search for the preference named browser.startup.homepage_override.mstone. double-click it and change its value to ignore.

You can check the home page setting:

  • Firefox > Preferences > General > Startup: Home page

Firefox supports multiple home pages separated by '|' (pipe) symbols.


If you do not keep changes after a restart or otherwise have problems with preferences, see:

Delete possible user.js and numbered prefs-##.js files and rename (or delete) 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 the current Firefox release.

You can use this button to go to the currently used Firefox profile folder:

  • Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)

I have no problem checking my home page. It hasn't changed.

That is not the problem. The problem is trying to ensure that Mozilla doesn't try to ignore my home page and open another page (the pushed release promo page) instead.

How do I prevent this?

Should I submit a trouble report?
