The issue could be not with Firefox, but with a newly installed program that sits in memory and constantly overwrites the home page. I would start with rebooting PC, and testing for the issue. Go to uninstall programs in Control Panel and see what was recently installed. I also would try to disable Firefox add ons.

I have used Firefox for about one year and have not changed my homepage from the first day. That homepage has now been taken down. So I have not tried to change homepage for a year. So all new programs and updates for the last year would be suspect. How do I figure out which one could be suspect?

I do not believe that I have any Firefox add ons. The menu/add ons does not indicate any. How do I find them and disable?

Let’s step back. Could you please try this: 1. Reboot your PC 2. Open Fierefox 3. Go to the new website you want to be home 4. Go Menu -> Options -> General tab 5. Press ‘Use Current Pages’ button and choose ‘When Firefox starts: Show my home page’ 6. Press ‘OK’ button 7. Close & Open Firefox, check if the issue go away or not

Considering what is the suspect – usually it is something that comes with free software. For example MS Office is not a suspect, but some free shopping bar that comes with good free soft could be doing this.

I did all 7 steps (have done this about 20 times by now) and when I start up Firefox the old homepage still comes up.

Hi jayhawk73,

There are some instructions in this article that might be helpful: How to fix preferences that won't save

Ok, hit Ctrl+Alt+Del button and go to Windows Task Manager. Check first Application tab if any suspicious apps are running. Then check for Processes – you could start killing one by one and check if it resolve the issue. Try to stay away from system processes. If the comp crashes then reboot.

Now, here is a work around (not perfect): create shortcut with the homepage and bookmark with home page and use it. Please let me know if you would like more details how to do this.

I started through the Windows Task Manager--big job...I like the work around...I will use it. Thanks!

Yep, all the best

There is software like Advanced SystemCare with its Surfing Protection feature that can protect files in the Firefox profile folder against changes. If you have such software then check the settings or uninstall this software.
