Mozilla loads with a site I visited early this month, despite having an URL set in my home page settings.

I have the google search page set in my options for the home page. The link is still in the field and it's still set to open to the home page. Mozilla opens to a health website logout screen every time I use it. When I hit the home page icon, Mozilla goes right to the home page I set (https://www.google.com/webhp?complete=0&hl=en). Why is it doing this and how might I stop it?

  1. In the Location bar, type about:config and press Enter. The "This might void your warranty!" warning page may appear.
  2. Click I'll be careful, I promise! to continue to the about:config page.
  3. Type browser.newtab.url in the search box to find it on the list.
  4. Double-click on browser.newtab.url and type in about:newtab in the window that pops up.

You can check if you have a user.js file in the Firefox profile folder that sets the browser.sessionstore.resume_session_once pref to true.

Your System Details list shows that you have a user.js file in the profile folder to initialize prefs each time Firefox starts. The user.js file is only present if you or other software has created this file and normally it wouldn't be there.

You can check its content with a plain text editor (right-click: "Open with"; do not double-click). The user.js file is read each time Firefox is started and initializes preferences to the value specified in this file, so preferences set via user.js can only be changed temporarily for the current session.

You can delete the user.js file if you didn't create this file yourself.


You can check for problems with the sessionstore.js file in the Firefox profile folder that store session data.

Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost and you will have to recreate them (make a note or bookmark them if possible).
