Useing Windows 10 and now whenever I open Firefox I am presented with a Yahoo page. Changing the preferences doesn't work. I'd be greatful for any ideas, I'm beginning to hate Yahoo.

Does changing your home page work even for a short time? You are familiar with the steps to set the home page on the Options page:

After fixing it, if you press Ctrl+n to launch a new window, does the correct home page appear? Or if you click the Home button on the toolbar?

If the change works until you exit Firefox and start it up again:

One thing to investigate is whether you have an optional settings file named user.js file in your profile folder (personal settings folder). If that is present, Firefox will use it at startup to override your saved preferences from the previous session. You can check and remove the file using the steps in this article: How to fix preferences that won't save.

Note: By default, Windows hides the .js file extension and some others. To work with files as accurately as possible, I suggest showing all extensions. This Microsoft support article has the steps (not sure it's still accurate for Windows 10): http://windows.microsoft.com/en-us/wi.../show-hide-file-name-extensions.

You might also check whether you have Advanced SystemCare or another program that monitors for browser settings changes and rolls them back.

If Firefox continuously ignores the home page setting or the previous section does not resolve the issue:

You may have a bad add-on. Here's my suggested procedure for tracking down and cleaning up bad add-ons, hijackers, and ad injectors. I know it seems long, but it's not that bad.

(1) Open the Windows Control Panel, Uninstall a Program. After the list loads, click the "Installed on" column heading to group the infections, I mean, additions, by date. This can help in smoking out undisclosed bundle items that snuck in with some software you agreed to install. Be suspicious of everything you do not recognize/remember, as malware often uses important or innocent sounding names to discourage you from removing it. Take out as much trash as possible here.

(2) Open Firefox's Add-ons page using either:

  • Ctrl+Shift+a
  • "3-bar" menu button (or Tools menu) > Add-ons
  • in the Windows "Run" dialog, type or paste
    firefox.exe "about:addons"

In the left column, click Plugins. Set nonessential and unrecognized plugins to "Never Activate".

In the left column, click Extensions. Then, if in doubt, disable (or Remove, if possible) unrecognized and unwanted extensions. Bear in mind that all extensions are optional, none come with Firefox, and you can learn more about them by checking their reviews on the Add-ons site.

Often a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.

Any improvement?

(3) You can search for remaining issues with the scanning/cleaning tools listed in our support article: Troubleshoot Firefox issues caused by malware. These on-demand scanners are free and take considerable time to run. If they finish quickly and especially if they require payment, you may have a serious infection. I suggest the specialized forums listed in the article in that case.

Success?

I found the file user.js and renamed it. This seems to have solved the problem. Thanks for the help
