I downloaded and installed the extension. I use Brave, which is built on Chromium, so the extension works just fine.

However, I noticed that you have to put your extensions library into developer mode in order to add the extension. No problem there.

But if I turn off developer mode, the extension goes away.

So do I have to keep my browser in developer mode permanently in order to use the extension? Or is there something I can do to enable it when not in developer mode?
