Resetting Firefox should fix this. The steps are in this article - Refresh Firefox - reset add-ons and settings. You can learn more about preferences not saving here - How to fix preferences that won't save.

Let me know how it goes, Michael

In case you are using "Clear history when Firefox closes":

  • do not clear the Site Preferences

Note that clearing "Site Preferences" clears all exceptions for cookies, images, pop-up windows, software installation, passwords, and other website specific data.


If you have software like Advanced SystemCare (Surfing Protection feature) that might reset some files to older versions to protect these files against changes then check the settings or uninstall this software.
