Google is changing the default search engine
I had Duck Duck Go set as the default search engine. Recently every time I turn on the computer Google is the default search engine. The OS is Ubuntu 20.04.3. I unchecked Google as a search engine. Do I need to delete any files that say Meta or take some other action? Thanks for your help.

If clearing the "Restore Default Search Engines" on the "Settings -> Search" page doesn't work, try to rename/remove search.json.mozlz4 in the Firefox profile folder with Firefox closed to rebuild the search engines registry.
You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page (Root directory).
- Help -> More Troubleshooting Information -> Profile Folder/Directory:
Windows: Open Folder; Linux: Open Directory; Mac: Show in Finder - https://support.mozilla.org/en-US/kb/profiles-where-firefox-stores-user-data
Firefox will rebuild search.json.mozlz4 from the built-in search engines.
You can try Firefox from the official Mozilla server if you currently use a version from the repositories of your Linux distribution to see if it behaves differently.
