Hi

What is the website address that you are using for DuckDuckGo?

Does it still happen in Troubleshoot Mode?

Have you enabled cookies for DDG?

It seems another user is having the same issue.

You could try clearing the cache then deleting Cookies. If that doesn't work, try right-clicking the site in History then Forget about this site. Make sure you have a backup record of your user name and password before doing that because they will be forgotten also.

If none of those fixes the issue, try restarting in troubleshoot mode.

Did my own searching to try to find the source / root of the problem, found the source: Its DuckDuckGo Privacy Essentials. When that is enabled, DuckDuckGo search engine is disabled In FireFox 117, for LinuxMint 21.2, FireFox set as default search engine, DuckDuckGo Privacy enabled this causes DuckDuckGo not to function.

When I install DuckDuckGo Privacy Essentials, it changes the default search engine to DuckDuckGo but it continues to work normally.

Does it still happen in a new profile? An easy way to test a new profile is to install Developer Edition and see if it happens there or refresh your existing profile.

I downloaded FireFox Developer Edition, installed DuckDuckGo Essentials, it works as it should. What to do to fix my already previously installed FireFox regular edition ???? Or if its not fixable, what to do to continue to use the regular edition of FireFox ????

Thank you dan

You can create a new profile for your regular Firefox. In the first article linked below there are sections telling you how to open the profile manager with Firefox open or closed.

See the other articles for copying data from the old profile to the new profile. You need to do that with Firefox closed.

Thank you very much for your very helpful info.

It seems to me that the Developer edition works faster than the standard edition. I've added my bookmarks and customization's, and would like to keep the Developer edition, and remove / delete the standard edition. Two questions:

1. Can I remove / uninstall the standard edition without damaging the Developer edition? 2. If yes, please tell me how to safely uninstall / remove the standard edition from my desktop LinuxMint computer.

Thanks dan

P.S. I understand that there are files to delete and files to possibly need editing in the profile directory.
