Had some computer difficulties. After some fixes I couldn't connect to the internet through Firefox. Found problem and fixed it, but not before reseting my firefox as a possible fix. Now I'm missing the preloaded Included search engines. In the window "Manage Search Engines", I no longer have any preloaded search engines. I can download one as an add-on, but I dont want to fish through all the different ones out there. I just want the searches that Firefox had pre-loaded. Is there a way to redownload and install those search engines for the toolbar without removing and reinstalling Firefox? Can I be directed to the links for those specific "what should be pre-loaded" add-ons to add them manually?

Do you still have the xml files of the default search engines in the searchplugins folder in the Firefox program folder?

  • (32 bit Windows) C:\Program Files\Mozilla Firefox\
  • (64 bit Windows) C:\Program Files (x86)\Mozilla Firefox\

If not then you need to reinstall Firefox.

You can find the latest Firefox release in all languages and for all Operating Systems here:


If they are there then delete the search.json file and a possible search.sqlite file in the Firefox Profile Folder.

You can use this button to go to the Firefox profile folder:

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.

Yes! I had the .xml files, then I found the "search.json" file and deleted it. All is restored. Thank you so much for the help!
