Surprisingly nobody mentioned all day that the ONLY permission this app has is to change your navbar setting. Chrome says that so clearly when you install it :)
The reason to install it is to have the convenience of a navbar search. Without it you will try a search or two and depending on what you searched for disappear because it's just not convenient enough to have to load another page every time you want to search.
But your target demographic is here telling you that with the extension requirement, they will try it zero times, because they don't want to change their default to a service they haven't tried yet.
A better idea would be to unblock search, show results to everyone regardless of browser defaults, and push hard for the extension install on the search results page once people can see the value prop you're offering.
Sorry to be off-topic, but you should really learn how to better communicate with your potential customers.
The little smiley face and saying it's shown "so clearly" has an extremely patronizing tone that is no way to build trust. Be more humble.
Nope, I’ll disappear immediately because it’s just not convenient enough to have to install an extension just to maybe try a search or two.
Why does it only happen with your extension and not the hundreds of others I have installed without this problem?
