I have tried everything I know of to resolve this. I have been working in I.T. and as a HTML/CSS/ASCII programmer for over 20yrs and I cannot figure this out. I have taken some pretty radical measures to prevent this and nothing seems to last more than a couple of hours. I've performed clean installs of Firefox and even Windows 8 and 10. I have been a user and supporter of Firefox for probably 15yrs now, but this is the most frustrating issue I've ever encountered. Even though I found articles posted by Mozilla Support acknowledging the problem starting back in Ver. 35 of Firefox there is still no solution. I've received cutting edge support such as "please see Configuration Options for Search"! Honestly, if it was that rudimentary would it even be considered a problem?

The resulting fallout of this is an overwhelming amount of service requests in to our I.T. support team. It has become such a problem in taking resources away from addressing "real I.T. problems" that no one is permitted to use Firefox on corporate owned desktops or laptops. That is approximately 370 devices that now are not allowed to have Firefox installed on them.

Very unfortunate, generally speaking I still believe Firefox is a superior product. However when it's use is costing us money in the way of resources it simply is unacceptable.

You may have ad / mal-ware. Further information can be found in the Troubleshoot Firefox issues caused by malware article.

Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.


After the problem is fixed, Bookmark and use this; Download the Mozilla Search Reset {web link} This add-on is very simple: on installation, it backs up and then resets your search preferences and home page to their default values, and then uninstalls itself. This affects the search bar, URL bar searches, and the home page.
