Trying to add a search engine addon


I thought I may repurpose this example:

But I ran into some issues.

  1. Following the documentation here:

In the Installing an example section, the linked video is private so I can’t watch it.

  1. Proceeding anyway, I loaded the temporary add-on and ran web-ext run. But the extension is greyed out and has an error about not being able to change or read data on the site.

  2. There is no new search engine appearing in the search preferences pane.

EDIT nevermind I realised I can add search engine by rightclicking the url and add that way.
