Privacy pass is literally the single most important feature and the whole reason I pay for Kagi, yet I cannot use it on Android.

As far as I can tell, there is no reason that the privacy pass would not be compatible with Firefox on Android. I suspect the idea is to steer users towards the Kagi app. However:

A) I have no reason to want to separate app for search. This is a corporate conceit; I'm paying for a service that is meant to be used in a browser. I prefer to use an open-source browser. I have no reason to evaluate, download, and use a separate app. It provides absolutely no utility to me as a user, only liability.
A) I do not have Google Play services or the Google Play store on my phone, so I can not install the app anyway.

Please make Kagi privacy pass work on Firefox Android.

I suspect it is as simple as setting a flag in the Mozilla Addon page...
