I believe the main feature is that it will sign you in when searching in private tabs, which works well.

You have to manually change your search engine to Kagi on Android at the moment. I guess that's a restriction to Firefox on Android.

Good, but it needs to have the option to be disabled and have a fallback in private browsing windows, because otherwise when you use it in private browsing windows, you encounter a sign-in screen and have to re-enter your search query in a different search engine. The nature of private browsing windows is that they do not store cookies, so there is no way to stay signed into Kagi in them. Works great in regular browsing windows though.

Works fine, but adds many nuisance context menus which cannot be disabled.

Fantastic companion to Kagi search, and works as expected with no hiccups that I've seen. The only thing that prevents me from rating it five stars is the lack of configuration items in the Manage Extension settings.

The primary setting I'd like to see there is a toggle to show/hide the Kagi Summarize entry in the right-click context menu for a page, since I've hit that once or twice by accident. A button on the main plugin panel to take us to all our Kagi account options instead of just the Summarize options would be handy, too.
