Wrong home page opens when I start Firefox - How to fix

Let us know if the issue still persists.

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.

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

• http://kb.mozillazine.org/Preferences_not_saved

If you do not have such software installed it is likely to be adware or malware. Look for unwanted toolbar or programs and uninstall them. Then scan with all the tools listed in this article
