This doesn't change the search engine, it attempts to redirect from whatever one is configured in the settings. It's very much an unreliable hack.

Unreliable indeed. It stops working half the time for no apparent reason and you have to go in and toggle settings to make it work again.

That was the old extension. New one is stable.

You are wrong. Your searches are still sent to the original search provider before the redirect extension takes over. It defeats any privacy Kagi could possibly provide.
