The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

1. Go to Firefox > Help > Troubleshooting Information.
2. Click the "Reset Firefox" button.
3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
4. Firefox will open with all factory defaults applied.

Further information can be found in the Refresh Firefox - reset add-ons and settings article.

hello, please try to install the search reset addon & restart firefox afterwards: https://addons.mozilla.org/firefox/addon/searchreset/

Is this happening with the search bar on the Navigation Toolbar or searching otherwise?

• searching via the location bar (pref: keyword.URL)
• search bar on the Navigation Toolbar
• search bar on the about:home page (pref: browser.search.defaultenginename)
• other search bar (e.g. added by extension)

You can also check the browser.search.defaultenginename pref on the about:config page and make sure that it is set to the default value Google.

• browser.search.defaultenginename

Thanks, folks! The "reset" fixed the problem.
